Elliptic flow of electrons from beauty-hadron decays extracted from Pb–Pb collision data at $$\sqrt{s_\mathrm{NN}} = 2.76\ \hbox {TeV}$$ sNN=2.76TeV

Abstract

Abstract We present a calculation of the elliptic flow of electrons from beauty-hadron decays in semi-central Pb–Pb collisions at centre-of-mass energy per colliding nucleon pair, represented as $$\sqrt{s_\mathrm{NN}}$$ sNN , of 2.76 TeV. The result is obtained by the subtraction of the charm-quark contribution in the elliptic flow of electrons from heavy-flavour hadron decays in semi-central Pb–Pb collisions at $$\sqrt{s_\mathrm{NN}} = 2.76\ \hbox {TeV}$$ sNN=2.76TeV recently made publicly available by the ALICE collaboration.
