| Abstract: Research into next-generation lepton colliders has emerged as a major priority internationally, with a ~10 TeV muon collider standing out as one of the most ambitious proposals. While such a machine would mark a transformative advance in accelerator science, realizing it demands breakthroughs in muon production, cooling, and rapid acceleration. In parallel with these technological developments, it is crucial to articulate and maximize the physics potential available throughout the staged R&D program. This talk highlights how a muon-collider–driven program can sustain and extend the U.S. community’s longstanding focus on neutrino physics, even as attention shifts toward high-energy collider applications. Opportunities include exploiting the intense muon-decay beam flux for adjacent neutrino-scattering experiments and exploring on-shell production and EFT channels enabled by neutrinos arising from muon parton distribution functions. Together, these possibilities demonstrate how a staged muon collider program can deliver impactful neutrino-focused science while building toward a future energy-frontier facility. |
