New Physics Search with the Optical Dump Concept at Future Colliders
Abstract
Beam-dump experiments offer an opportunity to search for new physics beyond the Standard Model of particle physics. In this work, we explore the use of a high-energy photon beam on a fixed target. Such photons can be produced via Compton backscattering when colliding high-energy electrons with a high-intensity laser pulse, such as in setups of strong-field quantum electrodynamics experiments. We present various options for implementing such photon sources at future facilities and discuss how the photons can be used to search for axion-like particles. We compare the projected sensitivities of the proposed options with existing constraints, projections from current experiments, and direct searches at future colliders.
