Just two and a half years into the Discovery Center a remarkable breakthrough has already been made. On the fourth of July 2012, Discovery Center scientists participating in the ATLAS experiment were able to announce the discovery of a new fundamental particle, the first such discovery for over seventeen years. This particle has all of the characteristics of the longsought Higgs Boson, which had eluded discovery for more than four decades. The Discovery Center was a hive of activity on the day of the announcement as TV crews, journalists and national radio presenters hurried around seeking interviews and opinion while constantly searching for the twenty second comment that could provide the sound-bite for the day. 2 | DISCOVERY CENTER OF EXCELLENCE The observation of a Higgs boson would confirm the existence of the Higgs mechanism, which gives a mass to some or all of the (currently) known fundamental particles. While the discovery of a Higgs-like particle was consequently one of the most celebrated events in the history of physics, the work of the Discovery Center covers a much wider range of topics than finding the Higgs Boson. We have already made great progress towards the determination of the spin and parity of this new particle, both of which will be crucially important in the final confirmation of the discovery of a Higgs Boson. We are also working full time on an analysis aiming to observe the decay of the new particle into a pair of what are known as tau-leptons. The Discovery Center has a leadership role in the study of such tau-leptons within the ATLAS experiment at CERN’s Large Hadron Collider (LHC), where one of our scientists is the convener of the dedicated tau working group. While the discovery of the Higgs Boson caught the public’s imagination and brought attention to our centre, the unseen work carried out behind the scenes is just as important as the headline-grabbing analyses. After three years, the centre has reached a size and strength that far surpasses our original expectations when we began in 2010. Discovery Center scientists are now working on the very latest data from the Planck satellite, analysing heavy ion collision data from CERN at ground-breaking energy densities, and determining new limits and bounds on theories that extend beyond the Standard Model. One feature that is common to all of these topics is the participation of the theory group, which is now fullyintegrated into the centre and interacts with all of the other research areas. The theory group also has a research programme of its own, and has in the past year made significant progress towards a formalism for what are known as twoloop perturbative calculations. These calculations will provide greatly improved theoretical predictions for many of the important underlying processes that occur at the LHC. Such predictions are vital to the proper understanding of the LHC data. A particularly striking example of the synergy that has emerged at the Discovery Center is a new formalism for analysing high particle-multiplicity heavy-ion collisions using highly optimised statistical tools taken from analyses of cosmological data. Although the first paper using such techniques was published during 2012, the expertise necessary to perform such an analysis currently only exists at the Discovery Center. The next step for this analysis will therefore be to publish a set of software tools that will allow others to more easily use our new techniques. There have been many other very impressive original developments at the centre, but rather than attempting to review them all here, I invite you to read about them yourself in the rest of this report. In doing so you will encounter topics at the cutting edge of scientific endeavour, topics in which the excitement and enthusiasm of the centre’s scientists is clear. You should also gain a small taste of our daily lives at the centre; we are very privileged to have the opportunity to carry out the research that we love, and we are always very happy to share it with you. January 2013 Peter H. Hansen Director of the Discovery Center ANNUAL REPORT 2012 | 3 EXPLORING THE UNIVERSE At the Discovery Center we are addressing some of the most fundamental questions about the Universe: from the grandest to the smallest scales, from billions of years to fractions of a second. We cover physics from the inflationary era at the beginning of time, the creation of particles, baryogenesis and the mysterious absence of anti-matter, the state of Quark Gluon Plasma in the hot infancy of the Universe, to the imprint of the birth of the Universe into the last scattering surface—observed today as the Cosmic Microwave Background. We study the first and the last of these using cosmological investigations, while the other subjects are explored through experimental and theoretical sub-atomic physics. In order to investigate the Cosmic Microwave Background, we must observe it. To this end the Discovery Center is involved in the on-going Planck mission. 2012 has been a year during which cosmologists from all over the world have eagerly awaited the of- ficial Planck data on the Cosmic Microwave Background which will be released in 2013. Much work has been done in preparation for this release which will be able to shed light on long-standing questions and fundamental issues in cosmology. Planck and parity In 2012, we have focused on subjects, which will be highly interesting to investigate with the coming Planck data. These include parity asymmetry of the Cosmic Microwave Background (that there might be a preferred direction in the Universe), foreground contamination from the galaxy or solar system which obscure the signal we are interested in, a new method for reconstruction of incomplete maps of the sky, and of course participation in official Planck research. Galactic Loops and correlation map - possible foregrounds A full understanding of foreground contamination is crucial for obtaining a clean picture of the primordial signal—and thus all research connected to the Planck data. The Discovery team is investigating multiple possible foregrounds, some of which could also be linked to the parity asymmetry. The cross disciplinary project on the application of cosmological methods and tools to heavy ion collisions data was finalized in 2012 with a publication in Phys.Rev.C. and a master thesis on the subject. Planck satellite 4 | DISCOVERY CENTER OF EXCELLENCE Planck meeting in Copenhagen ANNUAL REPORT 2012 | 5 Planck Haze The research at Discovery Center into the parity properties of the Cosmic Microwave Background is of such importance that it is now part of an official working group within the Planck experiment— ”Fundamental physics with Planck”—with Discovery scientist Pavel Naselsky as coordinator. In light of this, an official meeting of Planck scientists, “Fundamental Physics with Planck”, was held at the Discovery Center in June. 6 | DISCOVERY CENTER OF EXCELLENCE Coffee and discussions in the lounge In 2012 Planck found a peculiar signature in the galaxy named the “Planck Haze”. Although this Haze is known to be synchrotron radiation from the region around the galactic centre, it has very different characteristics to other known sources of synchrotron emission. Many possible explanations have been suggested, but none have been confirmed yet. One of the most interesting explanations is connected to dark matter. Dark matter annihilations are predicted to produce radiation of this nature within the galactic centre. However, the answer to the question of whether we have found a dark matter signature will have to wait for the release of the Planck Cosmic Microwave Background temperature and polarisation data, which is expected to spread more light on the subject. During the year the Discovery collaborator Subir Sarkar has joined the center, adding an interesting link between cosmology and high energy particle physics. His involvement in neutrino physics (through the IceCube experiment) also opens up for more research into “beyond standard model” physics. The miracle of matter The great questions of physics are simple. One such question is “Where did matter come from?” The world around us is made of protons, neutrons, and electrons—but we have known for more than 80 years that anti-protons, anti-neutrons and antielectrons exist. This initiates the question why there are so many particles, but very few anti-particles. Astronomers have searched the cosmos for galaxies or galactic clusters made of antiparticles, with no success. We conclude that for some reason more par- ANNUAL REPORT 2012 | 7 One of the first proton-lead collisions at the LHC, as observed by ALICE. ticles than anti-particles were produced in the early Universe, but we do not know why. This problem is known as baryogenesis, and although physicists have conceived of several possible solutions, none have been confirmed. genesis to the Center. The program was intense, with 23 talks over 2-3 days. We are now in the process of analysing LHC data in order to compare it to models of baryogenesis. ementary particles were closer together than they are today inside nuclei. Understanding in full the properties of the QGP has many very interesting research perspectives. To produce a QGP on Earth we collide heavy nuclei at relativistic speeds. Creating a quark-gluon plasma The Discovery Center is an ideal place to work on the conundrum of baryogenesis., and we aim to confront theories with data from the LHC. Indeed, already this year, we organised a conference on baryogenesis, which brought 30 experts on the theory of baryo- 8 | DISCOVERY CENTER OF EXCELLENCE Another striking era is that of Quark-Gluon Plasma (QGP). About 1 microsecond after the Big Bang, the entire Universe was small enough to fit between the Earth and the Sun today. With all the matter in the Universe compressed into such a small space, the el- In the last months of 2010 and 2011, the LHC collided lead-ions at energies more than ten times higher than any previous accelerator. A wealth of new results has already emerged from analysing these collisions. A test with proton-lead collisions in the autumn of 2012 has also already yielded exciting new results. With more proton-lead collision data coming in the first months of 2013, the LHC is sure to uncover new knowledge about the early universe. The Copenhagen contribution to the ALICE experiment is the Forward Multiplicity Detector, which provides a unique angular coverage that none of the other LHC experiments can match. Using this detector we have measured some of the basic properties of lead-lead collisions, such as the number of pro- ANNUAL REPORT 2012 | 9 duced particles (the multiplicity) and azimuthal correlations among these particles, known as azimuthal anisotropic flow. These measurements were presented at the Quark Matter 2012 conference. The multiplicity measurement tells us about the energy density in the collisions. A conservative estimate is that it exceeds 16 GeV/fm3, which is much higher than predictions from lattice QCD. The anisotropic flow results can be described in terms of a model based on hydrodynamics which allows us to put limits on the viscosity-entropy of the matter. Measurements thus far put the viscosity-entropy very close to zero, making the QGP one of the most perfect liquids ever studied. Furthermore, by looking at these observables in the rest frame of one of the colliding nuclei, we found an agreement with previous experiments at collision energies down to 1/100th that of the LHC. This effect is known as limiting fragmentation, and can be explained by assuming that the reaction partners are highly transparent and particle productions occurs due to the colourfields between the interacting partons. A major subject of heavy-ion analysis is the study of particle correlations. At the Discovery Center, new techniques utilising multi-particle correlations have provided us with more than 100 new observables. We are juggling enormous datasets on a daily basis. 10 | DISCOVERY CENTER OF EXCELLENCE ANNUAL REPORT 2012 | 11 Jet quenching, first observed by ATLAS at the LHC. One jet is clearly visible, while the other is smeared out in the opposite direction, as a result of the energy being absorbed by the hot matter created in the collision. These new observables allow us to place much better limits on models of the early period of nuclear collisions. As such this is an important step in understanding the details of the physics governing the time immediately after the collision. Discovering new phenomena The heavy ion collisions at the LHC have also brought us entirely new observations,.One such observation is the jet quenching reported by ATLAS. A jet is a spray 12 | DISCOVERY CENTER OF EXCELLENCE of highly correlated particles, and due to momentum conservation, a jet in one direction is usually accompanied by a jet in the opposite direction. However, at the LHC, ATLAS observed collisions with just one jet, with the remnants of a jet on the opposite side of the detector. This is known as jet quenching, and the physical interpretation is that the energy of one of the jets is absorbed by the QGP as it traverses the matter created in the collision. At heavy-ion experiments it is important to also collide a relatively small particle, like a proton, with the heavy nuclei. This allows us to disentangle effects present in binary collisions from the collective effects that we attribute to the QGP. From a small protonlead test in 2012 during which only 2 million collisions were recorded, ALICE and ATLAS have already been able to find signs of azimuthal anisotropic flow by performing an analysis of correlations. This has not previously been observed in such a small system, and work is currently ongoing to understand the na- ture of this effect. Millions of proton-lead events will be recorded at the beginning of 2013. The results from studying heavy-ion collisions not only tell us about the QGP state of the Universe, but also give us fundamental new knowledge about the strong force at very small distances, helping us better understand an important part of the Standard Model. At the high energies available at the LHC we are even able to observe heavy particles such as the Z and W bosons, which are associated with the weak force. ANNUAL REPORT 2012 | 13 From the Strong to the Weak Force Despite knowing the underlying theory of the strong and other forces, the experimental consequences are nevertheless not easily extracted. The challenge lies in taking into account the infinite series of quantum corrections. The link between theory and experiment is provided by scattering amplitudes, which describe the relative probabilities of different possible experimental outcomes. These amplitudes are therefore of crucial importance for the LHC. For example, at the LHC the amplitude for producing low mass particles such as pions, protons and neutrons is much larger than the amplitude for making Higgs bosons; this is one of the reasons why it is so hard to find the Higgs. 14 | DISCOVERY CENTER OF EXCELLENCE A major theme of interest in theoretical research on scattering amplitudes is that these amplitude calculations are much simpler than had previously been thought. This simplicity leads to an important consequence for physics at the LHC—the amplitudes can be calculated with a higher precision than we had hoped. Therefore we are able to make more precise predictions for LHC physics processes, allowing us to find more subtle signs of hidden new physics. On the theme of simplicity in scattering amplitude, Discovery Center members showed this year how a simple mathematical object, namely a group of symmetries, is linked to the computation of a class of amplitudes. SMat LHC meeting in Copenhagen in April, hosted by the Center. ANNUAL REPORT 2012 | 15 LEGO model of the ATLAS detector, designed by Discovery Center postdoc Sascha Mehlhase. We are also proud to report on a real technological breakthrough for performing precision computations of LHC processes. Namely, we described a simple new algorithmic method for computing subtle corrections to scattering amplitudes, which we believe will become important in the future of the LHC program. 16 | DISCOVERY CENTER OF EXCELLENCE The structure of the proton is a result of the strong force, and is described very accurately by structure functions. A speciality at the Discovery Center is the measurement of structure functions in heavy nuclei which differ from those in protons due to interactions between the nucleons. This is an ongoing collaboration between theorists and ALICE scientists, as well as involvement from ATLAS. Looking into the future The Center is thriving in a new era in which physics is once again dominated by experimental data. However, we also have an eye on the future. We are playing a role in shaping the future of experiments at CERN. One proposal for the future is the Large Hadron-Electron Collider (LHeC). The idea of the LHeC is to add to the LHC’s physics capabilities by building a new apparatus, which will allow us to collide accelerated protons and nuclei with electrons. The LHeC will complement and extend the LHC physics program. Key physics results will include a more detailed understanding of the Higgs boson as well as unprecedented new information on the structure of the proton (the so-called parton distribution functions or PDFs.) Because the LHC collides pro- ANNUAL REPORT 2012 | 17 tons, it is of crucial importance for us to understand PDFs. The centre has considerable expertise in this area, and has been contributing throughout the year, not only on the LHC, but also on the first steps towards the LHeC. A good understanding of the strong force is vital to the ATLAS research programme, including the search for new physics. Searches and precision measurements related to the weak force (including the the discovery of the Higgs particle—see middle pages) require good knowledge of the overwhelming backgrounds that arise from the strong force. The Dis- 18 | DISCOVERY CENTER OF EXCELLENCE covery Center has been leading the measurement of Triple Gauge Couplings from very rare events, which could potentially lead to discoveries of new phenomena that would otherwise be very hard to uncover. At the same time, the weak force carrying particles, the W and Z, are fantastic tools for studying the strong force. Beyond the Standard Model While the discovery of the Higgs completes the Standard Model, there remain several questions that cannot be answered within the framework of that model. Notable among these are an explanation for ANNUAL REPORT 2012 | 19 the observed tiny neutrino masses as well the origin and nature of the dark matter and dark energy observed today in the Universe. Despite the similar names, these latter two of these concepts are quite separate, and searches are being performed in data taken by the ATLAS experiment for possible dark matter candidate particles. These searches may also reveal further fundamental symmetries in the known laws of nature or, failing that, perform the equally important function of eliminating the possibility that such symmetries exist. Scientists from the Discovery Center are actively involved in many of these search analyses. We are also using the recent LHC data to search for other possible new features beyond the Standard Model. Such features include structure within quarks, which would indicate that they are not elementary particles, and lepto-quarks, which would mediate interactions between quarks and electrons. We have also been searching for evidence of Supersymmetry (SUSY), which under some conditions can provide a candidate for the origin of the dark matter that is known to dominate the Universe. We have been leading the search within ATLAS for such stable massive particles. Another area in which the Discovery Center performs research into physics beyond the Standard Model is the study of neutrinos, both theoretically and experimentally. Christine Hartmann, one of the younger 20 | DISCOVERY CENTER OF EXCELLENCE All the youngsters of the Discovery Center. Discovery Youngsters members of the centre, performs research into the behaviour of neutrinos. Christine studies the pattern of mixing that occurs between the three different flavours of neutrino. We have a poor understanding of the origin of this mixing, and Christine’s work pursued the idea that a particular symmetry may explain how the neutrino mixing arises. Students are a key asset for the centre. During 2012 several events were arranged by students for students, and with the full support of the centre. Three Discovery Youngster Symposia have been held for master and PhD students. During these Symposia, participating students gave short 15 to 20 minutes talks on a topic of their choice; the topic was usually related to their thesis or current work. The setting for these talks was informal, and they were delivered in such a way that students from other areas of physics could understand. Events such as these have given students an unique opportunity to improve their presentational skills ANNUAL REPORT 2012 | 21 and practise the communication of their results to others. Students also gained insight into the wide range of research that is carried out at the centre, shared knowledge with other students and developed their social and scientific networks. At these symposia visiting PhD students and post docs have also given talks. Another forum for informal networking and conversation has been frequent coffee meetings for youngsters of the center. These have been very popular during the year, sparking many interesting discussions about a broad range of subjects, from the origin of the Universe to monopoles in the LHC. Announcements of events and ad hoc communication between students of the center takes place on a separate mailinglist as well as a facebook group for “Discovery Youngsters”. The Discovery Center itself has a facebook page where photos of events, recent discoveries, graduations etc. are posted and reach a broad audience (e.g. over 375 people were engaged through the post of the Discovery group photo). 22 | DISCOVERY CENTER OF EXCELLENCE ANNUAL REPORT 2012 | 23 DISCOVERY PEOPLE 2012 Scientific Staff Alberto Guffanti Alejandro Alonso Anders Tranberg Ante BIlandizc Björn Stefan Nilsson Børge Svane Nielsen Casper Nygaard Carsten Søgaard Christian Holm Christensen Donal Francis O’Connell Florian Loebbert Frederik Orrellana Guido Marcorini Hans Bøggild Hans Hjersing Dalsgaard Hao Liu Ian Bearden Jaiseung Kim James Holmes Jens Jørgen Gaardhøje John Renner Hansen Joyce Myers Jørgen Beck Hansen Jørn Dines Hansen Kim Splittorf Konstantin Zoubous Kristjan Gulbrandsen Marek Chojnacki 24 | DISCOVERY CENTER OF EXCELLENCE Marger Simonyan Matti Herranen Mogens Dam Nele M.

Foto: Atlas Narko Politikere er vrede over politiets NÅR ANGREBET bliver så hårdt, er det fordi festivalen er en umuligh ed i det nyborgerlige verdensb illede. For de ved jo, at de bedste løsninger altid skabes af det frie marked. At al initiativ skabes i jagten på private profitter, og at effektivitet er umulig uden markedets usynlige hånd. Tanken om, at tusindvis af frivillige arbejder for at stable festivale n på benene, passer ikke ind i cost-benefit-analyserne. Tanken om, at en nonprofitorganisation kan skabe et professionelt arrangement, stemmer dårligt overens managem entkursets visdomsord. Men det er virkelighed hvert eneste år på Dyrskuepladsen i Roskilde. At det er fællesskab og ikke ulighed, der skaber dynamik. CEPOS OG dets efterbyrd af borgerlige meningsdannere har forsøgt at forklare paradokset om festivale ns succes med, at den selv er blevet til big business. Så passer verdensb illedet igen, og de kan også selv med god samvittighed blive en del af fællesskabet i nogle få sorgløse dage. For som alle andre er de velkomn ei Roskilde. Realiteten er, at det er lykkedes festivalen at bevare kernen af den ånd, der i 1971 for første gang samlede nogle hippier på en pløjema rk, og at udbrede og moderni sere denne ånd uden at komprom ittere den. Det er derfor, det hedder deltagere snarere end kunder i Roskilde . For uden den enkeltes deltagels e i fællesskabet var der slet ingen festival. Derfor er der grund til at takke de tusinder af mennesker, der igen i år viser, at fællesskabet kan skabe store resultater.
