Production of muons from heavy flavour decays at forward rapidity in pp and Pb-Pb collisions at = 2.76 TeV
arXiv:1205.6443 · doi:10.1103/PhysRevLett.109.112301
Abstract
The ALICE Collaboration has measured the inclusive production of muons from heavy flavour decays at forward rapidity, 2.5 < y < 4, in pp and Pb-Pb collisions at = 2.76 TeV. The -differential inclusive cross section of muons from heavy flavour 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 < < 10 GeV/. The suppression shows no significant dependence.
