【 摘 要 】

The J/ψ production cross-sections in proton-nucleus collisions at 5 TeV are measured using the LHCb detector. A sizable suppression is observed in pA forward collisions, while only a slight suppression is seen in pA backward collisions. The nuclear attenuation factor RpAand the forward-backward production ratio rFBare determined.
