Description
In this work we study long-lived light mediators which are well-motivated for connecting the dark sector with standard model particles. Experiments like ATLAS and CMS have placed strong bounds on heavy mediators with prompt decay, however the landscape of light long-lived mediators needs attention. Current experimental constraints have pushed the allowed mixing with the SM Higgs boson for scalar, and the kinetic mixing for vector mediators to very small values, indicating long lifetimes. We focus on the pair production of the long-lived mediators from SM Higgs decay in this work. We study the combined projected sensitivity of general purpose detectors like CMS along with dedicated detectors for LLP searches like FASER, MATHUSLA, CODEX-b, in hadron colliders and the prospect of identifying the underlying LLP model and extracting its parameters using such a combination.
