摘要：

We present measurements of the nuclear modification factor (R-AA) and azimuthal anisotropy (v(2)) of heavy-flavour decay electrons by the ALICE Collaboration at central rapidity in Pb-Pb collisions at root s(NN) = 2.76 TeV. A strong suppression of heavy-flavour decay electron production at high p(T) is observed in central Pb-Pb collisions, while non-zero v(2) is seen at low p(T) in semicentral collisions.
