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. 2014-09-23T12:13:48Z 2014-09-23T12:13:48Z 2013-06 2014-09-23T12:13:48Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Reproducció del document publicat a: http://dx.doi.org/10.1007/JHEP06(2013)064 Journal of High Energy Physics, 2013, vol. 6, num. 64, p. 1-30 http://dx.doi.org/10.1007/JHEP06(2013)064 cc-by (c) LHCb Collaboration, 2013 http://creativecommons.org/licenses/by/3.0/es/ info:eu-repo/semantics/openAccess Springer Verlag Articles publicats en revistes (Física Quàntica i Astrofísica)
