Contact Interactions at Future Circular Collider based Muon-Proton Colliders

Abstract

In recent years, high energy physicists have begun to show interest in such colliders again, introducing new approaches to solving some of the difficulties encountered in muon colliders. An advantageous situation of muon colliders over other lepton and hadron colliders emerges with solutions to these problems. For these reasons, we investigated four-fermion contact interactions at Future Circular Collider-based muon-proton colliders. Regarding the constructive and destructive interferences of contact interactions, we calculated the potentials of the FCC-based muon-proton colliders in terms of compositeness scale discovery, observation, and exclusion limits for the left-left, right-right, left-right, and right-left helicities interaction states. Our calculations have revealed that these colliders are great alternatives for investigating four-fermion contact interactions.
