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.eninfo:eu-repo/semantics/openAccess#BAŞV!Article1341110.1103/PhysRevLett.134.111903401924052-s2.0-105001179306Q1WOS:001498283800001Q10000-0001-9570-92550000-0003-1982-89780000-0001-7997-03060000-0002-0726-14520000-0002-0789-12000000-0003-0386-86330009-0008-1661-3537
