Megjegyzések:	A search for high-mass dimuon resonance production in association with one or more b quark jets is presented. The study uses proton-proton collision data collected with the CMS detector at the LHC corresponding to an integrated luminosity of 138 fb^(-1) at a center-of-mass energy of 13 TeV. Model-independent limits are derived on the number of signal events with exactly one or more than one b quark jet. Results are also interpreted in a lepton-flavor-universal model with Z' boson couplings to a bb quark pair (g_b), an sb quark pair (g_b[delta]_{bs}), and any same-flavor charged lepton (g_l) or neutrino pair (g_[nu]), with \|g_[nu]\| = \|g_l\|. For a Z' boson with a mass m_Z' = 350 GeV (2 TeV) and \|[delta]_{bs}\| < 0.25, the majority of the parameter space with 0.0057 < \|g_l\| < 0.35 (0.25 < \|g_l\| < 0.43) and 0.0079 < \|g_b\| < 0.46 (0.34 < \|g_b\| < 0.57) is excluded at 95% confidence level. Finally, constraints are set on a Z' model with parameters consistent with low-energy b --> sll measurements. In this scenario, most of the allowed parameter space is excluded for a Z· boson with 350 < m_Z' < 500 GeV, while the constraints are less stringent for higher m_Z' hypotheses. This is the first dedicated search at the LHC for a high-mass dimuon resonance produced in association with multiple b quark jets, and the constraints obtained on models with this signature are the most stringent to date.
