Search for Nuclear Modifications of <i>B</i><SUP>+</SUP> Meson Production in <i>p</i>-Pb Collisions at √<i>s</i><sub>NN</sub>=8.16 TeV

Description

Nuclear medium effects on B+ meson production are studied using the binary-collision scaled cross section ratio between events of different charged-particle multiplicities from proton-lead collisions. Data, collected by the CMS experiment in 2016 at a nucleon-nucleon center-of-mass energy of root s(NN) = 8.16 TeV, corresponding to an integrated luminosity of 175 nb(-1), were used. The scaling factors in the ratio are determined using a novel approach based on the Z -> mu(-) mu(+) cross sections measured in the same events. The scaled ratio for B+ is consistent with unity for all event multiplicities, putting stringent constraints on nuclear modification for heavy flavor.
