Overview

Introduction:
- - Jet production in pp, pA and AA collisions.
- - What can be learnt about high-energy-density QCD via jet physics in AA collisions ?

Results I: Leading hadron production in pp, dAu, AuAu @ RHIC:

- High pT hadro-production in baseline pp collisions (data vs. pQCD)
- High pT suppression in central AuAu: pT-, sqrt(s)-, reaction-plane dependence.
- Physics [Final state (FS) effects]: Parton energy loss ® QCD medium properties.

Results II: Jet production in QCD vacuum (pp) & cold QCD medium (dAu):

- Full jet reconstruction (pp).

- Dijets via dihadron Δφ correlations (pp, dAu).

- Extraction of jet properties: jT, kT

- Physics [Initial state (IS) effects]: multiple scattering in cold nuclear matter

Results III: Jet production in a hot & dense QCD medium (AA):

- Dijets: away-side disappearance: sqrt(s)-, reaction-plane dependence.

- Extraction of jet properties (jT, kT, “FFs”).

- Dihadron Δη correlations.

- Physics [Final state (FS) effects]: Jet quenching ® QCD medium properties.
