Abstract:
The production of J/ψ and $ \varUpsilon $ mesons in pp collisions at $ \sqrt{s}=8 $ TeV is studied with the LHCb detector. The J/ψ and $ \varUpsilon $ 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 $ \left( \varUpsilon \right) $ mesons. The J/ψ and $ \varUpsilon $ 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 .
