Signatures of Leptophilic Baryogenesis at Muon Colliders
Abstract
The baryon asymmetry of the Universe may be produced in a model with 3 Higgs fields, a Higgs Troika, without the need for a strong first order electroweak phase transition. The couplings of the new Higgs fields to Standard Model fermions are assumed in accord with the "Spontaneous Flavor Violation (SFV)" framework, in order to avoid large deviations from flavor physics constraints. We consider a leptophilic version of SFV and outline its potential signatures at future muon colliders, envisioned to be multi-TeV partonic center of momentum machines. Hence, they provide optimal venues to search for the leptophilic Higgs Troika baryogenesis mechanism. The projected reach for signals of the new scalars allows for probing the key components of the baryogenesis model at scales that accommodate cosmological requirements.
