Elliptic flow of heavy-flavour decay electrons in Pb-Pb collisions at SNN = 2.76 TeV with ALICE

Abstract

We present the elliptic ow v2 of electrons from the semi-leptonic decays of heavy- avour hadrons at mid-rapidity for semi-central (20-40% centrality) Pb-Pb collisions at SNN = 2.76 TeV measured with the ALICE detector. A positive v2 is observed at low pT in semi-central collisions. Comparisons with previous measurements obtained at lower collision energy at RHIC in Au-Au collisions at SNN = 0.2 TeV and with theoretical models are also presented.
