The production of J/ψ and υ mesons in pp collisions at √s = 8 TeV is studied with the LHCb detector. The J/ψ and υ 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 (υ) mesons. The J/ψ and υ 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 Title: Production of J/ψ and υ mesons in pp collisions at √s = 8 TeV Authors: R., Aaij B., Aveda M., Adinolfi Keywords: Flavor physics Heavy quark production Hadron-Hadron Scattering Particle and resonance production Issue Date: 2013 Publisher: Elsevier Abstract: The production of J/ψ and υ mesons in pp collisions at √s = 8 TeV is studied with the LHCb detector.
