| Sumario: | An inclusive search for long-lived exotic particles (LLPs) decaying to fnal states with a pair of muons is presented. The search uses data corresponding to an integrated luminosity of 36.6 fb−¹ collected by the CMS experiment from the proton-proton collisions at √s = 13.6 TeV in 2022, the frst year of Run 3 of the CERN LHC. The experimental signature is a pair of oppositely charged muons originating from a secondary vertex spatially separated from the proton-proton interaction point by distances ranging from several hundred µm to several meters. The sensitivity of the search benefts from new triggers for displaced dimuons developed for Run 3. The results are interpreted in the framework of the hidden Abelian Higgs model, in which the Higgs boson decays to a pair of long-lived dark photons, and of an R-parity violating supersymmetry model, in which long-lived neutralinos decay to a pair of muons and a neutrino. The limits set on these models are the most stringent to date in wide regions of lifetimes for LLPs with masses larger than 10 GeV. |
