Abstract: | 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 < 15GeV/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 σ(pp→D0X)=2460±3±130μbσ(pp→D+X)=1000±3±110μbσ(pp→D+sX)=460±13±100μbσ(pp→D∗+X)=880±5±140μb σ(pp→D0X)=2460±3±130μbσ(pp→D+X)=1000±3±110μbσ(pp→Ds+X)=460±13±100μbσ(pp→D∗+X)=880±5±140μb where the uncertainties are due to statistical and systematic uncertainties, respectively. |
