The production of J/ψ and Υ-mesons decaying into dimuon final state is studied at the LHCb experiment, with rapidity 1.5 < y < 4.0 or -5.0 < y < -2.5 and transverse momentum pT < 15 GeV/c, in proton-lead collisions at a proton-nucleon centre-of-mass energy of 5 TeV. The analysis is based on a data sample corresponding to an integrated luminosity of 1.6/nb. The forward-backward production ratio and the nuclear modification factor are determined for J/ψ and Υ(1S). Indication of forward backward production asymmetry is observed. There is also an indication of J/ψ and Υ(1S) production suppression with respect to proton-proton collisions in forward region and anti-shadowing effect in backward region. Results on vector boson production are also presented.
