Status and achievements of DISCOVERY 2010-2012

DISCOVERY II is a 5-year application aimed at exploring unknown mechanisms in particle physics and cosmology. It focuses on the exploration of electroweak symmetry breaking, the study of QCD at the TeV scale, and the search for connections between particle physics and cosmology. The project will be organized into four subgroups: experimental ATLAS and ALICE groups, theoretical phenomenology group, and theoretical cosmology group. Key milestones include optimizing LHC detectors, searching for new physics, and analyzing the cosmic microwave background radiation.

  6. What did wewrite ? DISCOVERY focuseson threescientificthemes: • The preciseexploration of the unknownmechanismthat breaks the electroweaksymmetry, alongwith the predictions for variousproposals for thismechanism, • The exploration of detailedexpectations of both the perturbative and nonperturbativeaspects of QCD at the TeV scale—the energyscaleappropriate for the Large HadronCollider • The search for connectionsbetweenparticlephysics and cosmologyin the discoveries made by the Planck mission’smeasurements studies of the fluctuations in the cosmicmicrowavebackground radiation. The work in DISCOVERY willbeorganized in foursubgroupsinteractingclosely with eachother: • The experimental ATLAS group, studying pp collisions at the energy and luminosityfrontier. • The experimental ALICE group, studyingnuclearcollisions at veryhighenergy. • The theoreticalphenomenologygroup, studying the consequences of the stronginteraction • The theoreticalcosmologygroup, analyzing and interpreting the cosmicmicrowavebackground as measured by the PLANCK satellite.

  7. The proposed Projects & Milestones • Optimizing the performance of the LHC detectors.  • Search for Higgs in the tau-tauchannel • The production and decay of electroweakvectorbosons. • GenericSearches for new physics • Boson-bosoncouplings • Partonshowers and hadronization. • Neural networkfit to structurefunctions.  • Furthereffects of small-x resummations.  • New QCD amplitude calculations.  • Particleproduction from hot and densequark-gluonmatter • Tomographyof Quark GluonMatter • Inflation and the fine structure of the earlyUniverse • The ionizationhistory of the cosmic plasma. 

  9. The HIGGS was Discovered Higgs ruled out by data for most masses But not here!!! Probability of observation in a model without Higgs is very small: Need Higgs at m=126 GeV to explain data! All masses below 560 GeV excluded at 95% confidence level except around 126 GeV. Data does not allow exclusion there!! DISCOVERY presentation by xx

  10. The QGP is hot, deconfined,dense and it flows Thermal radiation from QG: T= 304 MeV. Hottest system ever in human lab. Heavy quarksarealsosuppressed and they flow. => new transport theory for quark matter J/Psi regeneration=> directproof of deconfined large system Jet suppression

  11. Discovery from Discovery Center: Parityasymmetry of the CMB. Parity asymmetry of the CMB: • PT(r)=-T(r)-most represented ! From micro- to macro scale • Parity violation in Weak interactions P(r)=-r Pψ(r)=±ψ(r) Possible explanations: Theoretical prediction from Inflation WMAP 5 and 7 Local violation of Copernicus principle Chance probability: 2/1000 ! Non-trivial topology of space and time New physics, New sources of Emissivity from the space , Improvement of the data sets and creditability of the PLANCK mission. Local foreground . Debris of the solar system formation. Effects of systematic and calibration DISCOVERY presentation by xx

  19. Summary • Thegrant from the Danish National Research Foundation has been decisive for bringingoutstandingyoungscientists to the Discovery Center and for initiatingnew physicsacrosspreviousborders • The flexibility has beenessential for hiring the best at the right time and combining with othergrants: a fantasticperiod of growth • Many diverse activities: A wealth of excitingresultsalreadydelivered, and much more to come • The Discovery Center is much more than the sum of the parts: a transformation of the highenergy research landscape in Denmark DISCOVERY presentation by xx
