dc.description.abstractRatios of cross sections, ??Z ? c jets?=??Z ? jets?, ??Z ? b jets?=??Z ? jets?, and ??Z ? c jets?= ??Z ? b jets? in the associated production of a Z boson with at least one charm or bottom quark jet are measured in proton-proton collisions at ffiffi s p ¼ 13 TeV. The data sample, collected by the CMS experiment at the CERN LHC, corresponds to an integrated luminosity of 35.9 fb?1, with a fiducial volume of pT > 30 GeV and j?j < 2.4 for the jets, where pT and ? represent transverse momentum and pseudorapidity, respectively. The Z boson candidates come from leptonic decays into electrons or muons with pT > 25 GeV and j?j < 2.4, and the dilepton mass satisfies 71 < mZ < 111 GeV. The measured values are ??Z ? c jets?=??Z ? jets? ¼ 0.102 0.002 0.009, ??Z ? b jets?=??Z ? jets? ¼ 0.0633 0.0004 0.0015, and ??Z ? c jets?=??Z ? b jets? ¼ 1.62 0.03 0.15. Results on the inclusive and differential cross section ratios as functions of jet and Z boson transverse momentum are compared with predictions from leading and next-to-leading order perturbative quantum chromodynamics calculations. These are the first measurements of the cross section ratios at 13 TeV.en_US
