Title: Trigger strategy for displaced muon pairs following the CMS phase II upgrades

Abstract

We show that the phase II upgrade of the CMS tracking detector could enable the experiment to trigger on very low mass $$\mathcal{O}$$(1 GeV) displaced muon pairs with minimal $$p_T$$ cuts. As a result, CMS can be competitive with LHCb when searching for low mass displaced exotics originating from heavy flavor decays. The method can also be applied to signatures without muons but with a moderate amount of missing transverse energy, $$H_T$$ or multiple displaced vertices in the event.
