Description
The main goal of the ALICE experiment is the investigation of the properties of strongly-interacting matter in a very high density deconned state, that should be formed in Pb-Pb collisions.
The measurement of the heavy avour production cross section in p-p collisions at the LHC will allow to test perturbative QCD calculations in a new energy regime. The p-p collisions data are also important as a reference for the study of dense matter eects in Pb-Pb collisions, where heavy quarks are expected to be sensitive probes for the QCD medium properties, as they are formed at shorter time scale than the medium itself. The nuclear modication factor (RAA), obtained by comparing p-p and Pb-Pb pT -dierential distributions, allows to measure the eect of in-medium energy loss. The status of open heavy avour measurements in p-p collisions at 7 TeV and Pb-Pb collisions at 2.76 TeV with the ALICE experiment will be presented. The results of the single lepton analyses (electrons at central rapidity, muons at forward rapidities) and D mesons reconstruction in their hadronic decays will be discussed.
