    Title: Heavy-flavour measurements in pp and Pb-Pb collisions with the ALICE experiment at the CERN LHC

    Description: The ALICE experiment at the CERN LHC has conducted first systematic studies of heavy-flavour hadron production in pp collisions at sqrt(s) = 7 TeV and in Pb-Pb collisions at sqrt(s_NN) = 2.76 TeV. In pp collisions the differential production cross sections of D mesons at mid-rapidity, as well as the cross sections for electrons and muons from semileptonic heavy-flavour hadron decays at mid- and forward-rapidity, respectively, have been measured. These data provide a crucial testing ground for perturbative QCD calculations in the new LHC energy regime. In Pb-Pb collisions, the nuclear modification factor R_AA(p_t) has been measured for D mesons and for leptons from heavy-flavour decays, indicating energy loss of heavy quarks in the partonic medium produced in Pb-Pb collisions at the LHC. The strong interaction of charm quarks with this medium might also generate a non-zero elliptic flow of D mesons as first studies of the azimuthal anisotropy of D^0-meson production suggest.

    Title: Open heavy flavour measurements with the phenix experiment at rhic
    Author: Averbeck, Ralf
    Subject: Physics;
    Description: The PHENIX experiment has measured single electron spectra at RHIC in protonproton (pp), deuterongold (dAu), and goldgold (AuAu) collisions at an available energy per nucleonnucleon pair of . Contributions from photonic sources, i.e. Dalitz decays of light mesons and photon conversions, are subtracted from the inclusive spectra. The remaining non-photonic single electron spectra are dominated by semileptonic decays of particles carrying heavy flavour. Implications of these systematic measurements for heavy flavour production in cold and hot nuclear systems are discussed.
