Resum

The production of prompt D+ and D+ s mesons is studied in proton-lead collisions at a centre-of-mass energy of √ sNN = 5.02 TeV. The data sample corresponding to an integrated luminosity of (1.58 ± 0.02)nb−1 is collected by the LHCb experiment at the LHC. The diferential production cross-sections are measured using D+ and D+ s candidates with transverse momentum in the range of 0 < pT < 14 GeV/c and rapidities in the ranges of 1.5 < y∗ < 4.0 and −5.0 < y∗ < −2.5 in the nucleon-nucleon centre-of-mass system. For both particles, the nuclear modifcation factor and the forward-backward production ratio are determined. These results are compared with theoretical models that include initial-state nuclear efects. In addition, measurements of the cross-section ratios between D+, D+ s and D0 mesons are presented, providing a baseline for studying the charm hadronization in lead-lead collisions at LHC energies.
