Measurement of heavy-flavour decay muon production at forward rapidity in pp and Pb-Pb collisions at sqrt(s_NN)=2.76 TeV with the ALICE experiment

The ALICE experiment measured the heavy-flavour production in the semi-muonic decay channel at forward rapidities ($2.5<y<4$) in pp and Pb--Pb collisions at $\sqrt{s_{{NN}}} = 2.76$ TeV. We report on the first results on the $p_{\rm T}$-differential cross-sections in pp collisions as well as on the nuclear modification factors as a function of the transverse momentum and centrality.
