A search for pair production of new light bosons decaying into muons in proton-proton collisions at 13 TeV
A search for new light bosons decaying into muon pairs is presented using a data sample corresponding to an integrated luminosity of 35.9 fb−1 of proton-proton collisions at a center-of-mass energy √s = 13 TeV, collected with the CMS detector at the CERN LHC. The search is model independent, only...

| Summary: | A search for new light bosons decaying into muon pairs is presented using a data sample corresponding
to an integrated luminosity of 35.9 fb−1 of proton-proton collisions at a center-of-mass energy √s =
13 TeV, collected with the CMS detector at the CERN LHC. The search is model independent, only requiring
the pair production of a new light boson and its subsequent decay to a pair of muons. No significant
deviation from the predicted background is observed. A model independent limit is set on the product of
the production cross section times branching fraction to dimuons squared times acceptance as a function
of new light boson mass. This limit varies between 0.15 and 0.39 fb over a range of new light boson
masses from 0.25 to 8.5 GeV. It is then interpreted in the context of the next-to-minimal supersymmetric
standard model and a dark supersymmetry model that allows for nonnegligible light boson lifetimes. In
both cases, there is significant improvement over previously published limits |
