Open heavy–flavour and quarkonium measurements with ALICE at the LHC

The ALICE detector provides excellent capabilities to study heavy quark (i.e. charm and beauty) production in proton{proton (pp) and heavy{ion collisions (AA) at the Large Hadron Collider (LHC). In ALICE, open heavy{ avour hadron production is studied through the hadronic decays of D mesons at central rapidity ( j y j < 0 : 9), and in the semi{leptonic decays of charm and beauty hadrons both at mid{rapidity and at forward rapidity (2 : 5 < y < 4). Quarkonia are measured in their di{electron and di{muon decay channels in the central barrel and in the muon spectrometer respectively, reaching in both cases zero transverse momentum. The latest results on open heavy{ avour and quarkonium production in pp ( p s = 2.76 TeV and p s = 7 TeV) and PbPb ( p s NN = 2.76 TeV) collisions are presented
