Measurement of the production of high-pT electrons from heavy-flavour hadron decays in Pb-Pb collisions at sNN=2.76Â TeV

Electrons from heavy-flavour hadron decays (charm and beauty) were measured with the ALICE detector in Pb-Pb collisions at a centre-of-mass of energy sNN=2.76TeV. The transverse momentum (pT) differential production yields at mid-rapidity were used to calculate the nuclear modification factor RAA in the interval 3
