Measurement of the Bc-meson production fraction and asymmetry in 7 and 13 TeV pp collisions LHCb Collaboration Calvo Gómez, Míriam Camboni, Alessandro Coquereau, Samuel Garrido Beltrán, Lluís Gascón Fora, David Gironella Gironell, P. Graciani Díaz, Ricardo Graugés Pous, Eugeni Manera Escalero, R. Vázquez Gómez, Ricard Vilasis-Cardona, Xavier Marin Benito, Carla Física de partícules Cromodinàmica quàntica Particle physics Quantum chromodynamics The production fraction of the Bc-meson with respect to the sum of B- A nd B0 mesons is measured in both 7 and 13 TeV center-of-mass (c.m.) energy pp collisions produced by the Large Hadron Collider (LHC), using the LHCb detector. The rate, approximately 3.7 per mille, does not change with energy, but shows a transverse momentum dependence. The Bc-Bc+ production asymmetry is also measured and is consistent with zero within the determined statistical and systematic uncertainties of a few percent. 2020-05-22T11:42:30Z 2020-05-22T11:42:30Z 2019-12-13 2020-05-22T11:42:30Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Reproducció del document publicat a: https://doi.org/10.1103/PhysRevD.100.112006 Physical Review D, 2019, vol. 100, num. 11, p. 112006 https://doi.org/10.1103/PhysRevD.100.112006 info:eu-repo/grantAgreement/EC/H2020/792684/EU//pANUCSTR info:eu-repo/grantAgreement/EC/H2020/639068/EU//BSMFLEET info:eu-repo/grantAgreement/EC/H2020/714536/EU//PRECISION (c) American Physical Society, 2019 info:eu-repo/semantics/openAccess American Physical Society Articles publicats en revistes (Física Quàntica i Astrofísica)
