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 unites strong groups in:Theory, Fundamental Particle Physics,Quark Gluon Plasma Physics Cosmic Microwave Radiation Physics, …which most places rarely work together.

Summary

• 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)
