Abstract:
A search for long-lived particles decaying into muon pairs is performed using
proton-proton collisions at a center-of-mass energy of 13 TeV, collected by the CMS experi-
ment at the LHC in 2017 and 2018, corresponding to an integrated luminosity of 101 fb−1.
The data sets used in this search were collected with a dedicated dimuon trigger stream
with low transverse momentum thresholds, recorded at high rate by retaining a reduced
amount of information, in order to explore otherwise inaccessible phase space at low dimuon
mass and nonzero displacement from the primary interaction vertex. No significant excess
of events beyond the standard model expectation is found. Upper limits on branching
fractions at 95% confidence level are set on a wide range of mass and lifetime hypotheses
in beyond the standard model frameworks with the Higgs boson decaying into a pair of
long-lived dark photons, or with a long-lived scalar resonance arising from a decay of a
b hadron. The limits are the most stringent to date for substantial regions of the parameter
space. These results can be also used to constrain models of displaced dimuons that are not
explicitly considered in this paper.
