Production of Muons from Heavy Flavor Decays at Forward Rapidity in pp and Pb-Pb Collisions at √sNN=2.76  TeV

The ALICE Collaboration has measured the inclusive production of muons from heavy-flavor decays at forward rapidity, 2.5<y<4, in pp and Pb-Pb collisions at √sNN=2.76  TeV. The pt-differential inclusive cross section of muons from heavy-flavor decays in pp collisions is compared to perturbative QCD calculations. The nuclear modification factor is studied as a function of pt and collision centrality. A weak suppression is measured in peripheral collisions. In the most central collisions, a suppression of a factor of about 3–4 is observed in 6<pt<10  GeV/c. The suppression shows no significant pt dependence.
