urn:hdl:2445/119379 Measurements of prompt charm production cross-sections in pp collisions at √s = 13 TeV Badalov, Alexey Garrido Beltrán, Lluís Gascón Fora, David Graciani Díaz, Ricardo Graugés Pous, Eugeni Marin Benito, Carla Picatoste Olloqui, Eduardo Rives Molina, Vicente José LHCb Collaboration Interaccions d'hadrons Quarks Hadron interactions Quarks 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. 2018-01-29T13:07:16Z 2018-01-29T13:07:16Z 2016-03-22 2018-01-29T13:07:16Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Reproducció del document publicat a: https://doi.org/10.1007/JHEP03(2016)159 Journal of High Energy Physics, 2016, vol. 2016, num. 159 https://doi.org/10.1007/JHEP03(2016)159 https://doi.org/10.1007/JHEP09(2016)013 cc-by (c) LHCb Collaboration et al., 2016 http://creativecommons.org/licenses/by/3.0/es info:eu-repo/semantics/openAccess Springer Verlag Articles publicats en revistes (Física Quàntica i Astrofísica)
