Production of muons from heavy-flavour hadron decays in pp collisions at √s = 5.02 TeV
Production cross sections of muons from semi- leptonic decays of charm and beauty hadrons were measured at forward rapidity (2.5 < y < 4) in proton-proton (pp) collisions at a centre- of-mass energy √s = 5.02 TeV with the ALICE detector at the CERN LHC. The results were obtained in an extended transverse momentum interval, pT<2, 20> GeV/c, and with an improved precision compared to previous measurements performed in the same rapidity interval at centre-of-mass energies √s = 2.76 and 7 TeV. The pT- and y-differential production cross sections as well as the pT-differential production cross section ratios between different centre-of-mass energies and different rapidity intervals are described, within experimental and theoretical uncertainties, by predictions based on perturbative QCD.
