Physics with the NCC Heavy Ion (A+A)

photon Jet : energy loss vs L, ε reaction plane resolution: Si Barrel, Forw Si, NCC, MPC

χC states: screening, deconfinement(?)

p+A direct-photons: Qs vs x, Q2

understand what we are measuring

spin (p+p); ΔG (?) photon-jet W (isolation?)

CDR – what physics understanding/simulations ? Physics Understanding

pA – understand the variables spin – understand the measurements

Simulations In PISA (pp, pAu, AuAu)

reconstructing π0

direct photons What are the real backgrounds?

Pile up? Need Fast simulation High pt π0

Find the money…
