Description
Light new physics has become a particularly active research direction, in particular with the proposed dedicated Forward Physics Facility at CERN, as well as with the upcoming FASER detector measurements. In the talk, we will describe how the small lifetime regime of light long-lived particles in the non-minimal BSM scenarios based on renormalizable portals can be covered in the FPF using the secondary particle production. Additionally, we will describe prospects of indirect detection (ID) of long-lived particles in a model employing heavy thermal DM particle, LLP and a light mediator. The resulting non-local ID effects distinguish such a scenario from ordinary searches for WIMPs, while complementary FPF searches for the light mediator will allow us to explore even such an extended scenario.
