The J/ψ and TeX mesons are reconstructed in the μ + μ − decay mode and the signal yields are determined with a fit to the μ + μ − invariant mass distributions. The analysis is performed in the rapidity range 2. 0 < y < 4. 5 and transverse momentum range 0 < p T < 14 (15) GeV/c of the J/ψ TeX mesons. The J/ψ and TeX production cross-sections and the fraction of J/ψ mesons from b-hadron decays are measured as a function of the meson p T and y.31 p.application/pdfengcc-by (c) LHCb Collaboration, 2013http://creativecommons.org/licenses/by/3.0/es/QuarksTeoria quàntica de campsRelativitat (Física)QuarksQuantum field theoryRelativity (Physics)info:eu-repo/semantics/article6289902014-09-23info:eu-repo/semantics/openAccess
