| 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 experiment 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. | ||

The dimuon invariant mass distribution is shown in bins of ${l_\mathrm {xy}}$ as obtained from selected dimuon events in data where both muons are isolated with $ {{p_{\mathrm {T}}} ^{\mu \mu}} < $ 25 GeV: (upper left) 0.0 $\leq {l_\mathrm {xy}} < $ 0.2 cm ; (upper right) 0.2 $\leq {l_\mathrm {xy}} < $ 1.0 cm ; (middle left) 1.0 $\leq {l_\mathrm {xy}} < $ 2.4 cm ; (middle right) 2.4 $\leq {l_\mathrm {xy}} < $ 3.1 cm ; (lower left) 3.1 $ \leq {l_\mathrm {xy}} < $ 7.0 cm; (lower right) 7.0 $\leq {l_\mathrm {xy}} < $ 11.0 cm. The distribution expected for a representative $h_{\mathrm{b}}\to \phi X$ signal model with $m_{\phi} = $ 2 GeV and $c\tau _{0}^{\phi}=$ 1 mm is overlaid. The signal event yield corresponds to a value of the branching fraction product $\mathcal {B}(h_{\mathrm{b}}\to \phi X) \, \mathcal {B}(\phi \to \mu \mu) = $ 1.2$\times $10$^{-8}$, equal to the median expected exclusion limit at 95% CL set in this paper (see Section 7), and is multiplied by a factor of 100 for display purposes. The vertical gray bands indicate mass ranges containing known SM resonances, which are masked for the purpose of this search. |

| Summary |
| A search for displaced dimuon resonances has been performed using proton-proton collisions at a center-of-mass energy of 13 TeV, collected by the CMS experiment at the LHC in 2017 and 2018, corresponding to an integrated luminosity of 101 fb$^{-1}$. The data sets used in this search are collected using 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 beyond the standard model expectation is found, and the data are used to set constraints on a wide range of mass and lifetime hypotheses for models of physics beyond the standard model where a Higgs boson decays to a pair of long-lived dark photons, or where a long-lived scalar resonance arises from the decay of a b hadron. These constraints are the most stringent to date for substantial regions of the parameter space. |
