Prompt $\Lambda_c^+$ baryons and $D^0$ meson production cross-section and nuclear modification in p Pb collisions at $\sqrt {S_{NN}}=$ 5.02TeV with the LHCb detector

$\Lambda_c^+$ baryons and $D^0$ mesons are studied in p Pb collisions at $\sqrt {S_{NN}}=$ 5.02TeV. The nuclear modification factor and forward-backward cross-section asymmetry are measured in order to study the cold nuclear matter effects. The prompt $\Lambda_c^+$ production cross-section is compared to that of the prompt $D^0$ mesons, providing insights into the hadronisation mechanism of charmed hadrons.
