A search for long-lived particles decaying into muon pairs is performed usingproton-proton collisions at a center-of-mass energy of 13 TeV, collected by theCMS experiment at the LHC in 2017 and 2018, corresponding to an integratedluminosity of 101 fb$^{-1}$. The data sets used in this search were collectedwith a dedicated dimuon trigger stream with low transverse momentum thresholds,recorded at high rate by retaining a reduced amount of information, in order toexplore otherwise inaccessible phase space at low dimuon mass and nonzerodisplacement from the primary interaction vertex. No significant excess ofevents beyond the standard model expectation is found. Upper limits onbranching fractions at 95% confidence level are set on a wide range of mass andlifetime hypotheses in beyond the standard model frameworks with the Higgsboson decaying into a pair of long-lived dark photons, or with a long-livedscalar resonance arising from a decay of a b hadron. The limits are the moststringent to date for substantial regions of the parameter space. These resultscan be also used to constrain models of displaced dimuons that are notexplicitly considered in this paper.
