Abstract
Production of prompt $D^0$ mesons is studied in proton-lead and lead-proton collisions recorded at the LHCb detector at the LHC. The data sample corresponds to an integrated luminosity of $1.58 \pm 0.02 nb^{−1}$ recorded at a nucleon-nucleon centre-of-mass energy of $\sqrt s_{NN} = 5$ TeV. Measurements of the differential cross-section, the forward-backward production ratio and the nuclear modification factor are reported using $D^0$ candidates with transverse momenta less than 10 GeV/c and rapidities in the ranges $1.5 < y^ ∗ < 4.0$ and $−5.0 < y^ ∗ < −2.5$ in the nucleon-nucleon centre-of-mass system.
