Query: Elliptic flow of electrons from beauty-hadron decays extracted from
  Pb--Pb collision data at $\sqrt{s_{\rm NN}}$ = 2.76 TeV   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 $\sqrt{s_{\rm NN}}$, 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 \snn = 2.76 TeV recently made publicly available by the ALICE
collaboration.
