Multi-TeV Signals of Higgs Troika Model

Abstract

We consider a model of baryogenesis that requires extending the Standard Model by two additional multi-TeV Higgs doublets that do not break electroweak symmetry. Adopting the ``Spontaneous Flavor Violation" framework, we can arrange for the heavy Higgs states to have significant couplings to light quarks. This allows for the heavy scalars to be resonantly produced at a future 100 TeV $pp$ collider and discovered in di-jet and top-pair final states up to masses of $\mathcal{O}$(10 TeV). The same mass range can also lead to signals in flavor experiments. Together, these measurements can play a complementary role in probing the physics involved in this Higgs Troika baryogenesis scenario.
