The production of J/ψ and mesons in pp collisions at TeV is studied with the LHCb detector. The J/ψ and 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 mesons. The J/ψ and 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.

Abstract

The production of J/ψ and mesons in pp collisions at TeV is studied with the LHCb detector. The J/ψ and 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 mesons. The J/ψ and 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.
