The data were collected using dedicated dimuon triggers with low transverse momentum thresholds, recorded with a high-rate data scouting trigger stream. This data stream retains a reduced amount of information at the high-level trigger, to explore otherwise inaccessible phase space at low multimuon invariant mass and nonzero displacement from the primary interaction vertex. No significant excess of events above the standard model prediction is found. Upper limits on branching fractions at 95% confidence level are set for a wide range of mass and lifetime hypotheses in several beyond the standard model frameworks, where the Higgs boson decays into long-lived dark photons or into dark partons that produce showers containing long-lived particles, or where a long-lived scalar resonance is produced from the decay of a b hadron. The resulting constraints improve and extend existing ones in large regions of the parameter space.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.169181.v1/t1","@type":"Dataset","description":"Overall signal efficiency as measured for the HAHM signal model with $m_{Z_{D}} = 2$ GeV, as a function of the...","name":"Figure 4a"},{"@id":"https://doi.org/10.17182/hepdata.169181.v1/t2","@type":"Dataset","description":"Overall signal efficiency as measured for the HAHM signal model with $m_{Z_{D}} = 5$ GeV, as a function of the...","name":"Figure 4b"},{"@id":"https://doi.org/10.17182/hepdata.169181.v1/t3","@type":"Dataset","description":"Overall signal efficiency as measured for the HAHM signal model with $m_{Z_{D}} = 12$ GeV, as a function of the...","name":"Figure 4c"},{"@id":"https://doi.org/10.17182/hepdata.169181.v1/t4","@type":"Dataset","description":"Overall signal efficiency as measured for the HAHM signal model with $m_{Z_{D}} = 20$ GeV, as a function of the...","name":"Figure 4d"},{"@id":"https://doi.org/10.17182/hepdata.169181.v1/t5","@type":"Dataset","description":"Four-muon invariant mass distributions of selected events with a four-muon system selected in the multivertex category, for data and different,...","name":"Figure 5a"},{"@id":"https://doi.org/10.17182/hepdata.169181.v1/t6","@type":"Dataset","description":"Four-muon invariant mass distributions of selected events with a four-muon system selected in the overlapping vertex category, for data and...","name":"Figure 5b"},{"@id":"https://doi.org/10.17182/hepdata.169181.v1/t7","@type":"Dataset","description":"Dimuon invariant mass distributions of selected events with a single, isolated muon pair with $p_{T}^{\\mu\\mu} > 25$ GeV.
