Abstract

The prompt production of Λ _c ⁺ baryons is studied in proton-lead collisions collected with the LHCb detector at the LHC. The data sample corresponds to an integrated luminosity of 1.58 nb ⁻¹ recorded at a nucleon-nucleon centre-of-mass energy of sNN=5.02 TeV. Measurements of the differential cross-section and the forwardbackward production ratio are reported for Λ _c ⁺ baryons with transverse momenta in the range 2 < p _T < 10 GeV/c and rapidities in the ranges 1.5 < y ^∗ < 4.0 and −4.5 < y ^∗ < −2.5 in the nucleon-nucleon centre-of-mass system. The ratio of cross-sections of Λ _c ⁺ baryons and D ⁰ mesons is also reported. The results are compared with next-to-leading order calculations that use nuclear parton distribution functions.[Figure not available: see fulltext.]
