Measurements of prompt charm production cross-sections in pp collisions at s = 5 √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 D 0, D +, D + , 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 D 0 and D + and 1 < p T < 10 GeV/c for D + 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 $$ {array}{l}σ ( pp→ {D}^0X)=1004± 3± 54μ b,\\ {}σ ( pp→ {D}⁺X)=402± 2± 30μ b,\\ {}σ ( pp→ {D}_s⁺X)=170± 4± 16μ b,\\ {}σ ( pp→ {D}⁺X)=421± 5± 36μ b,{array} $$ where the uncertainties are statistical and systematic, respectively.
