28<strong>Phy</strong>sics of jet quenching• Crucial question:– Does parton evolution inmedium look anything likea “normal” parton shower??• Attempt to distinguish– Weakly coupled radiative +collisional energy loss– Strongly coupled/nonperturbativequenching⇒Expect strong couplingeffects to produce “non-QCD-like” jets⇒Then should measurelarge jet suppression
Prospects• 7 TeV p-p– LHC magnets already being ramped to 3.5 TeV– 7 TeV operation on few week time-scale– Goal for 2010-2011, 1 fb-1⇒Unprecedented sample of jets out to ~ TeV• 2.6 TeV Pb+Pb– Few weeks of low-luminosity ~10 -25 fall 2010.<strong>Phy</strong>sics• High-statistics studies of parton showers generatedby high-Q 2 processes• Unique studies of jet quenching in Pb+Pb⇒ New physics of radiating color charge in medium⇒ Crucial probe of quark-gluon plasma for T /Tc > 2• Low-x physics (which I didn’t have time to discuss)29
