High pT in a strongly interacting medium

• Initial- (CGC) vs final-state (QGP) medium effects :

• Experimental handles on high pT particle production:

  • Depletion of high pT inclusive hadrons (jet leading particles)
  • Attenuation / absorption of jets (“jet quenching”): photon-tagged jets,
  • direct  vs fragmentation  ...
  • Modification of angular correlations between jet products
  • Changes in particle composition
