Search for long-lived particles in final states with displaced dimuon vertices in pp collisions at √s= 13 TeV with the ATLAS detector

Popis výsledku v původním jazyce

A search is performed for a long-lived particle decaying into a final state that includes a pair of muons of opposite-sign electric charge, using proton-proton collision data collected at s=13  TeV by the ATLAS detector at the Large Hadron Collider corresponding to an integrated luminosity of 32.9  fb-1. No significant excess over the Standard Model expectation is observed. Limits at 95% confidence level on the lifetime of the long-lived particle are presented in models of new phenomena including gauge-mediated supersymmetry or decay of the Higgs boson, H, to a pair of dark photons, ZD. Lifetimes in the range cτ=1–2400  cm are excluded, depending on the parameters of the model. In the supersymmetric model, the lightest neutralino is the next-to-lightest supersymmetric particle, with a relatively long lifetime due to its weak coupling to the gravitino, the lightest supersymmetric particle.
