Abstract
These proceedings summarize the LHCb measurements of charm- and beauty-hadron production in pPb collisions. The studies are made down to very low-pT of the observed heavy-flavor hadrons using fully reconstructed decays. Nuclear matter effects are quantified via nuclear modification factors and forward-backward production ratios, suggesting a strong suppression for the forward rapidity and no suppression for the backward rapidity. The results help to constrain nuclear parton distribution distribution down to Bjorken-x∼ 10^−5. The charm pair production is first measured in pPb data, which comfirms the enhancement of double parton scattering in pPb collisons. These data provide important inputs to understand the Quark-Gluon Plasma formed in heavy-nucleus collisions.
