Measurements of prompt charm production cross-sections in pp collisions at √s=5 TeV

Production cross-sections of prompt charm mesons are measured using data from pp collisions at the LHC at a centre-of-mass energy of 5 TeV. The data sample corresponds to an integrated luminosity of 8.60 ± 0.33 pb⁻¹ collected by the LHCb experiment. The production cross-sections of D⁰, D⁺, D_s⁺, and D^∗+ mesons are measured in bins of charm meson transverse momentum, p_T, and rapidity, y. They cover the rapidity range 2.0 < y < 4.5 and transverse momentum ranges 0 < p_T< 10 GeV/c for D⁰ and D⁺ and 1 < p_T< 10 GeV/c for D_s⁺ and D^∗+ mesons. The inclusive cross-sections for the four mesons, including charge-conjugate states, within the range of 1 < p_T< 8 GeV/c are determined to be(Formula Presented.)where the uncertainties are statistical and systematic, respectively.[Figure not available: see fulltext.].
