Search for long-lived particles decaying to a pair of muons in pp collisions at s= 13.6 TeV with 2022 data
Abstract: An inclusive search for long-lived exotic particles decaying to a pair of muons is presented. The search uses data collected by the CMS experiment at the CERN LHC in proton-proton collisions at s= 13.6 TeV in 2022 and corresponding to an integrated luminosity of 36.7 fb1. The experimental signature is a pair of oppositely charged muons originating from a common secondary vertex spatially separated from the pp interaction point by distances ranging from several hundred μm to several meters. The results are interpreted in the frameworks 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 results show substantial improvements as compared to the analysis performed using data taken at s= 13 TeV, particularly at low masses and long lifetimes, mainly because of improved triggers for displaced muons and offline analysis refinements.
