Abstract

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 sqrt{s} = 5.02 TeV with the ALICE detector at the CERN LHC. The results were obtained in an extended transverse momentum interval, 2 < pT< 20 GeV/c, and with an improved precision compared to previous measurements performed in the same rapidity interval at centre-of-mass energies sqrt{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.

Highlights

Based calculations at both forward and central rapidities in a large transverse momentum range
The ratios of D-meson production cross sections between different rapidity intervals and centre-of-mass energies recently measured by the ALICE and LHCb experiments [13, 15, 16] are described by pQCD-based predictions within uncertainties
The measurement of heavy-flavour production cross sections in pp collisions provides the necessary baseline for the corresponding measurements in proton-nucleus and nucleus-nucleus collisions

Summary

Introduction

Based calculations at both forward and central rapidities in a large transverse momentum (pT) range. The ratios of D-meson production cross sections between different rapidity intervals and centre-of-mass energies recently measured by the ALICE and LHCb experiments [13, 15, 16] are described by pQCD-based predictions within uncertainties. The present measurements cover the interval 2 < pT < 20 GeV/c, where the beauty contribution is expected to dominate over the charm contribution in the high pT region i.e. for pT > 5 GeV/c [2] They are complementary to those performed at the same centre-of-mass energy by the LHCb Collaboration for D-meson species in a kinematic region limited to hadron pT < 10 GeV/c [16].
