英文摘要 | The production of b+, b-0 and lambda(0)(b), hadrons is studied in proton-lead collisions at a center-of-mass energy per nucleon pair of root(nn)-n-s t = 8.16 tev recorded with the lhcb detector at the lhc. the measurement uses a dataset corresponding to an integrated luminosity of 12.2 +/- 0.3 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 +/- 0.5 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 lambda(0)(b), over b-0 production cross sections is reported and is consistent with the corresponding measurement in pp collisions. |
