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.

Abstract
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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
