Abstract The production of J/ψ mesons is studied with the LHCb detector using data from pp collisions at s=2.76TeV corresponding to an integrated luminosity of 71nb1. The differential cross-section for inclusive J/ψ production is measured as a function of its transverse momentum pT. The cross-section in the fiducial region 0<pT<12GeV/c and rapidity 2.0<y<4.5 is measured to be 5.6±0.1(stat)±0.4(syst)μb, with the assumption of unpolarised J/ψ production. The fraction of J/ψ production from b-hadron decays is measured to be (7.1±0.6(stat)±0.7(syst))%.
