Description
Within proton-lead collisions collected by the LHCb detector at nucleon-nucleon center-of-mass energy of 5 and 8.16 TeV, a rich set of open charm hadrons is observed with abundant statistics. Thanks to the LHCb forward acceptance that is complementary to general purpose detectors and excellent performance in particle reconstruction and identification, these charm states are studied down to zero $p_\mathrm{T}$ with overwhelming precision in heavy ion data. Presented in this talk is the measurements of production of charm mesons and baryons reconstructed in exclusive hadronic final states. The results on nuclear modification factors will give stringent test on the nuclear parton distribution function and parton saturation models. The hadronization mechanism of charm quarks are also studied. The production ratio of stranged $\Xi_c^+$ and $D_s^+$ over $D^+$ or $D^0$ will be presented, in order to search for possible strangeness enhancement in small-system collisions.
