Francesca Acanfora, U Mass, Amherst [HET Seminar] Belle II and the Muon Collider: how lepton colliders can find New Physics

Thursday 25 Jun 2026, 11:00 → 13:00 US/Eastern

Small Seminar Room

We can divide the last few generations of Particle Physicists in those who dreamt, those who built and those who operated a "future" collider. My generation will be the one running the last years of LHC and Belle II while planning, building and turning on the next collider(s). Undoubtedly, we will have to keep in mind all the lessons learned at the LHC but future high energy lepton colliders will gain a vital advantage from looking back at existing lepton machines, notably Belle II. The Muon Collider and Belle II could be operating in the same years in the upcoming decades, for an exceptional coverage of the scale of New Physics from the MeV to the PeV. The Particle Physicist who will want to find New Particles will have to explore the entirety of this spectrum. After shortly hinting at the nodes of similarity and continuity between the two lepton machines, I will provide an example of this strategy by presenting two promising channels for New Physics: a Heavy Vector Triplet roadmap to discovery at the Muon Collider and a displaced Dark-Higgs hunt at Belle II.
