Summary
Large amount of high precision large-pT hadron production data at RHIC after 5 years of operation allows to quantitatively address jet physics in
QCD medium (w/o full jet reco).
Details of suppressed hadro-production in central Au+Au provide:
- stringent constraints on underlying physics.
- direct access to the density and transport properties of the QCD medium.
Is jet quenching due to radiative energy loss in a QGP ?
Good agreement with calculations on:
- Magnitude, √s, pT, centrality, (light) species dependence
Some tests are weak at present:
- Few details missing in system-size dependence
- no sharp test of L2 dependence yet.
- unsuppressed (but jet-like) baryon production points to (sthg. more than) recombination ?
- heavy quark energy loss larger than expected
LHC will provide enormous reach and qualitatively new observables (full jet reco, jet-jet, jet-g,Z correlations ...)
