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 [superscript +] μ [superscript −] decay mode and the signal yields are determined with a fit to the μ [superscript +] μ [superscript −] invariant mass distributions. The analysis is performed in the rapidity range 2. 0 < y < 4. 5 and transverse momentum range 0 < p [subscript 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 [subscript T] and y.
