Measurements of heavy-flavour decay leptons in pp, p-Pb, and Pb-Pb collisions with ALICE

Abstract

We present measurements of electrons and muons originating from the semi-leptonic decays of heavy-flavour hadrons at central and forward rapidities with ALICE in pp ( = 2.76 and 7 TeV), p-Pb ( = 5.02 TeV), and Pb-Pb ( = 2.76 TeV) collisions. The measured pT-differential production cross sections in pp collisions, the nuclear modification factors in p-Pb and Pb-Pb, and the v2 measurements in Pb-Pb collision are disgusted. In addition, the angular correlation distribution between heavy-flavour decay electrons and charged particles, measured in p-Pb collisions, is shown. The results are compared to their corresponding theoretical predictions.
