Elliptic flow of heavy-flavour decay electrons in Pb-Pb collision at $\sqrt{s_{\mathrm{NN}}}$ = 2.76 TeV with ALICE

Abstract

We present the elliptic flow $v_2$ of electrons from the semi-leptonic decays of heavy-flavour hadrons at mid-rapidity for semi-central ($20-40$ centrality) Pb-Pb collisions at $\sqrt{s_{\mathrm{NN}}}$ = 2.76 TeV measured with the ALICE detector. A positive $v_2$ is observed at low $p_{\mathrm{T}}$ in semi-central collisions. Comparisons with previous measurements obtained at lower collision energy at RHIC in Au-Au collisions at $\sqrt{s_{\mathrm{NN}}}$ = 0.2 TeV and with theoretical models are also presented.
