"Measurements of open heavy-flavour production with ALICE at LHC"

4:00pm, RLM 9.222

Abstract: Heavy quarks (charm and beauty) are used as a probe to investigate the properties and the behavior of a high energy density strongly interacting matter, called Quark-Gluon Plasma, which is expected to be produced in relativistic heavy-ion collision (Pb-Pb). In p-Pb collisions, heavy-quark production could be sensitive to cold nuclear matter effects, such as the modification of parton distribution functions in nuclei compared to nucleons and energy loss in cold nuclear matter. In pp collisions they provide an important test of pQCD calculations and also provide some insight into the role of multi-parton interactions (MPI) in these collisions. The measurement in pp collisions also provides a crucial baseline for heavy-ion collisions.

Heavy flavour production is studied with the ALICE detector at LHC by reconstructing D0, D+, D＊+ and D+s mesons via their hadronic decay channels and, alternatively, via the measurement of leptons (electrons and muons) from semi-leptonic decays of heavy-flavour hadrons. I will present measurements of open heavy flavour production in pp, p-Pb and Pb-Pb collisions with the ALICE detector.
