Abstract:

An inclusive search for long-lived exotic particles (LLPs) decaying to final 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 first 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 benefits 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.
