High pT identified particles in PHENIX: data vs. theory.

Overview

High pT @ RHIC: Motivation

High pT @ RHIC: Motivation (cont'd)

High pT neutral pion spectra

Identified p,pbar high pT spectra

High pT pi0 @ 200 GeV: AuAu vs pp

Nuclear modification factor: sqrt(s_NN) dependence

High pT suppression: Central/peripheral

Centrality dependence of pi0 suppression

Hadron composition at high pT: R_AA(p) vs R_AA(pi)

Hadron composition at high pT: p/pi ratios

Hadron composition at high pT: pbar/p ratios

High pT @ RHIC: a theorist "guide"

Magnitude of the suppression

pT dependence of the suppression (I)

pT dependence of the suppression (II)

Parton shadowing does not seem to play a role (?)

but ... what do we really know(*) about gluon shadowing ?

Cronin enhancement does seem to play a role

Energy loss + Shadowing + Cronin = flat R_AA

High pT suppression explainable too due to hadronic final-state interactions(*) !?

pT dependence of suppression: Npart scaling ?

Centrality dependence of suppression: Npart scaling ?

Parton recombination and high pT "chemistry"
