Description

The observation of the decay in flight of exotic long-lived particles with $c\tau >\mathcal{O}(1\mathrm{m})$ would be a compelling signature for many Beyond Standard Model (BSM) scenarios. The sensitivity to such particles of existing LHC experiments, however, is limited by complicated trigger environments, high backgrounds, and/or geometric restrictions to the forward region, leaving a significant region of phase-space unexplored. A dedicated, shielded, transverse experiment is therefore essential to search for many BSM scenarios above the electroweak scale at the high-luminosity LHC (HL-LHC).

We here briefly present the physics case for a dedicated, transverse, zero-background long-lived particle detector at the HL-LHC.
