Aspen 2025: BSM at the MuSIC

At the Aspen Center for Physics program Empowering the New Vision in High Energy Physics, I presented “BSM at the Muon Synchrotron Ion Collider: Let the MuSIC play!”

A Muon (Synchrotron) Ion Collider (MuSIC) can be the successor to the Electron-Ion Collider at Brookhaven National Laboratory, as well as the ideal demonstrator facility for a future multi-TeV Muon Collider. Besides its rich nuclear physics and Standard Model particle-physics programs, the MuSIC with a TeV-scale muon beam offers a unique opportunity to probe new physics. In particular, the relevant searches have the potential to surpass current experimental limits and explore new regimes of the parameter space for a variety of beyond-the-Standard-Model scenarios including lepton-flavor-violating leptoquarks, muonphilic vector-boson interactions, axion-like particles coupling to photons, and heavy sterile neutrinos. Depending on the particular case, the sensitivity of the searches in the MuSIC may span a wide range of energy scales, from sub-GeV particles to few-TeV new-physics mediators. Our analysis demonstrates that the MuSIC can strike a powerful chord in the search for new physics, thanks to a unique combination of features that amplify its capabilities.
