Morphology of CMB and HIC. Commonality and perspectives. P. Naselsky , PLANCK scientist
DISCOVERY presentation by xx 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 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)
