; A; bstract; ; ; A search for a new neutral gauge boson, Z; ′; , produced in association with one or two jets, including at least one b jet, and decaying into a pair of muons is presented. The analysis uses proton-proton collision data collected with the CMS detector at; ; ; $$ sqrt{s}=13 $$; ; ; s; ; =; 13; ; ; ; TeV, corresponding to an integrated luminosity of 138 fb; ; −; 1; ; . No significant deviation from background expectations is observed. Upper limits at 95% confidence level on the product of cross section, branching fraction to dimuons, acceptance, and efficiency, from 0.2 to 2 fb, are set for Z; ′; boson masses between 125 and 350 GeV. Process-dependent products of acceptance and efficiency, and model-independent limits on the signal yield are provided. These are the only results to date in the 125–200 GeV mass range and the most stringent for b quark fusion production modes in the 200–350 GeV range, complementing inclusive Z; ′; boson searches.;
