| Abstract: A search is presented for a new neutral boson, Z', produced in association with one or two jets, including at least one b jet, and decaying into two muons. Current exclusion bounds on this signature are looser than those for Z' produced via light quark fusion. The analysis is performed using data collected in 2016--2018 with the CMS detector in proton-proton collisions at $ \sqrt{s}= $ 13 TeV and corresponding to an integrated luminosity of 138 fb$ ^{-1} $. No significant deviation from background expectations is observed. Limits at 95% CL on the product of cross section, branching fraction, and acceptance are set, ranging from 0.2 to 2 fb, for Z' masses between 127 and 352 GeV. Model-independent upper limits on signal yield and generator-process-dependent acceptances are provided. | ||
