Description:
  'The production of $B^+$, $B^0$ and $\mathit{\Lambda}_b^0$ hadrons is studied in proton-lead collisions at a center-of-mass energy per nucleon pair of $\sqrt{s_\mathrm{NN}} = 8.16\,\mathrm{TeV}$ recorded with the LHCb detector at the LHC. The measurement uses a dataset corresponding to an integrated luminosity of $12.2\pm 0.3\,\mathrm{nb}^{-1}$ for the case where the proton beam is projected into the LHCb detector (corresponding to measuring hadron production at positive rapidity) and $18.6\pm 0.5\,\mathrm{nb}^{-1}$ for the lead beam projected into the LHCb detector (corresponding to measuring hadron production at negative rapidity). Double-differential cross-sections are measured and used to determine forward-backward ratios and nuclear modification factors, which directly probe nuclear effects in the production of beauty hadrons. The double-differential cross-sections are measured as a function of the beauty-hadron transverse momentum and rapidity in the nucleon-nucleon center-of-mass frame. Forward-to-backward cross-section ratios and nuclear modification factors indicate a significant nuclear suppression at positive rapidity. The ratio of $\mathit{\Lambda}_b^0$ over $B^0$ production cross-sections is reported and is consistent with the corresponding measurement in $pp$ collisions.'
