Measurements of prompt charm production cross-sections in pp collisions at s = 13 √s=13 TeV

Production cross-sections of prompt charm mesons are measured with the first data from pp collisions at the LHC at a centre-of-mass energy of 13 TeV. The data sample corresponds to an integrated luminosity of 4.98 0.19 pb -1 collected by the LHCb experiment. The production cross-sections of D 0 , D + , D + s , and D * + mesons are measured in bins of charm meson transverse momentum, p T , and rapidity, y, and cover the range 0 < p T < 15 GeV/c and 2.0 < y < 4.5. The inclusive cross-sections for the four mesons, including charge conjugation, within the range of 1 < p T < 8 GeV/c are found to be
