Jet quenching studies with the ALICE detector

In central Pb-Pb collisions at the LHC, jet rates are expected to be high at energies at which ALICE can reconstruct jets over the background of the underlying event. This will open the possibility to quantify the effect of partonic energy loss through medium induced gluon radiation, jet quenching, by detailed measurement of the modification of the longitudinal and transverse structure of identified jets. For lower energies, E/sub T/<30 GeV, high-p/sub T /momentum spectra and particle correlations will be used to study jet modifications. In the intermediate energy region, 20 GeV<E/sub T/<50 GeV, ALICE will use gamma-jet correlations to tag jets. Monte Carlo simulations will be presented that strongly indicating that, in order to obtain probes sensitive to the properties of the QCD medium, it is mandatory to measure the high-p/sub T/ parton fragments together with the low-pcharged particle tracking capabilities of ALICE with Deltap /p<10% from 100 MeV-100 GeV combined with the proposed electromagnetic calorimeter for ALICE, EMCAL, represent an ideal tool for jet, quenching studies at the LHC.
