3
DISCOVERY A Unique Center with Unique Opportunities Direct and unique access to data from the most powerful experiments available today : – The Large Hadron Collider (LHC) at CERN exploring p+p and Pb+Pb collisions at unprecedented high energies (ATLAS and ALICE experiments) – The Planck satellite mission with unique resolution and sensitivity of the sky. DISCOVERY presentation by xx33/5/2012 DISCOVERY unites strong groups in: Theory, Fundamental Particle Physics, Quark Gluon Plasma Physics Cosmic Microwave Radiation Physics, …which most places rarely work together.

18
Summary 18 A new method to analyse the event morphology in Heavy Ion and Particle physics has been proposed. Toy model analysis suggest good resolution for collective phenomena (elliptic flow) and point sources (jets) Next steps: – Full simulation with realistic event generator and detector transport code – Develop analysis for additional physics effects – Analyse ALICE events from LHC Pb+Pb (2.76 A.TeV)
