Abstract
We study the pair production of the long-lived mediator particles from the decay of the standard model Higgs boson and their subsequent decay into standard model particles. We compute the projected sensitivity, both model independently and with a minimal model, of using the muon spectrometer of the CMS detector at the HL-LHC experiment for ggF, VBF, and VH production modes of the Higgs boson and various decay modes of the mediator particle, along with dedicated detectors for long-lived particle searches like CODEX-b and MATHUSLA. Subsequently, we study the improvement with the FCC-hh detector at the 100 TeV collider experiment for such long-lived mediators, again focusing on the muon spectrometer. We propose dedicated long-lived particle detector designs for the 100 TeV collider experiment, detector for long-lived particles at high energy of 100 TeV, and study their sensitivities. © 2022 authors.
