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 D0, D+, Ds +, and D*+ mesons are measured in bins of charm meson transverse momentum, pT, and rapidity, y, and cover the range 0 < pT < 15GeV/c and 2.0 < y < 4.5. The inclusive cross-sections for the four mesons, including charge conjugation, within the range of 1 < pT < 8 GeV/c are found to be (Formula presented.) where the uncertainties are due to statistical and systematic uncertainties, respectively.I metadati presenti in IRIS UNICA sono rilasciati con licenza Creative Commons CC0 1.0 Universal, mentre i file delle pubblicazioni sono protetti da diritto d'autore, salvo diversa indicazione.
