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 $p_T>30$ GeV and $|\\eta|<2.4$ for the jets, where $p_T$ and $\\eta$ represent transverse momentum and pseudorapidity, respectively. The Z boson candidates come from leptonic decays into electrons or muons with $p_T>25$ GeV and $|\\eta|<2.4$, and the dilepton mass satisfies $71<m_{Z}<111$ GeV. The measured values are $\\sigma(Z+\\text{c jets})/\\sigma(Z+\\text{jets}) = 0.102 \\pm 0.002 \\pm 0.009$, $\\sigma(Z+\\text{b jets})/\\sigma(Z+\\text{jets}) = 0.0633 \\pm 0.0004 \\pm 0.0015$, and $\\sigma(Z+\\text{c jets})/\\sigma(Z+\\text{b jets}) = 1.62 \\pm 0.03 \\pm 0.15$. 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.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.94288.v1/t1","@type":"Dataset","description":"Unfolded R(c/j) cross section ratio versus jet transverse momentum","name":"Figure 3 (left)"},{"@id":"https://doi.org/10.17182/hepdata.94288.v1/t2","@type":"Dataset","description":"Unfolded R(c/j) cross section ratio versus Z boson transverse momentum","name":"Figure 3 (right)"},{"@id":"https://doi.org/10.17182/hepdata.94288.v1/t3","@type":"Dataset","description":"Unfolded R(b/j) cross section ratio versus jet transverse momentum","name":"Figure 4 (left)"},{"@id":"https://doi.org/10.17182/hepdata.94288.v1/t4","@type":"Dataset","description":"Unfolded R(b/j) cross section ratio versus Z boson transverse momentum","name":"Figure 4 (right)"},{"@id":"https://doi.org/10.17182/hepdata.94288.v1/t5","@type":"Dataset","description":"Unfolded R(c/b) cross section ratio versus jet transverse momentum","name":"Figure 5 (left)"},{"@id":"https://doi.org/10.17182/hepdata.94288.v1/t6","@type":"Dataset","description":"Unfolded R(c/b) cross section ratio versus Z boson transverse momentum","name":"Figure 5 (right)"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins1776758?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/94288"}],"inLanguage":"en","name":"Measurement of the associated production of a Z boson with charm or bottom quark jets in proton-proton collisions at $\\sqrt{s}=$ 13 TeV","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins1776758?version=1","version":1}
