Description
The ALICE experiment is designed to study the properties of the high energy density medium formed in ultra-relativistic heavy-ion collisions. The measurement of open charm and beauty production in heavy ion collisions has an important role in the investigation, since it gives access to the mechanisms of heavy-quark propagation and energy loss in the hot and dense QCD matter. Heavy-flavour measurements in pp collisions are fundamental in this analysis, since they provide a crucial reference for the study of the effects in heavy-ion collisions. Moreover, they have an interest on their own since they allow for a precise test of the perturbative quantum chromodynamics in the high energy domain.
With the ALICE detector, heavy-flavour production can be studied via reconstruction of D mesons through hadronic decay channels at mid-rapidity and inclusive reconstruction of heavy flavours in the semi-electronic and semi-muonic decay channel at central and forward rapidity, respectively. This presentation will be mainly focused on the results in pp collisions at a centre of mass energy of 2.76 and 7 TeV.
