Heavy-flavour decay lepton measurements in pp, p-Pb, and Pb-Pb collisions with ALICE at the LHC

摘要

We present the measurements of electrons and muons from the semi-leptonic decays of heavy-flavour hadrons measured in the central and forward rapidity regions with ALICE in pp (s/(1/2) = 2.76 TeV and 7 TeV), Pb-Pb ((~sNN)/(1/2) = 2.76 TeV), and p-Pb ((~sNN)/(1/2) = 5.02 TeV) collisions at the LHC. The pT-differential production cross section in pp collisions, the elliptic flow in Pb-Pb collisions, and the nuclear modification factor in Pb-Pb and p-Pb collisions are shown. The results are compared to theoretical predictions.
