Speaker
Description
New light particles may be produced in large numbers in the far-forward region at the LHC and then decay to dark matter, which can be detected through its scattering in far-forward experiments. In the talk, we will discuss the discovery potential of such far-forward searches for light dark matter scattering off electrons or nuclei in an emulsion or liquid argon detector placed on the beam collision axis during HL-LHC. For illustration, we will focus on a popular example of invisibly-decaying dark photons, which decay to dark matter through 𝐴′→𝜒𝜒, while further prospects for probing BSM interactions of neutrinos will also be presented. These results motivate the construction of far-forward emulsion and liquid argon (FLArE) detectors, as well as a suitable location to accommodate them, such as the proposed Forward Physics Facility.
