Multi-TeV Signals of Higgs Troika Model

TL;DR

This paper explores a multi-TeV Higgs model for baryogenesis, proposing that heavy Higgs states could be produced and detected at future colliders and flavor experiments, providing a new avenue for testing baryogenesis theories.

Contribution

It introduces a Higgs Troika model with two additional Higgs doublets that can be tested at future colliders and flavor experiments, linking collider signals with baryogenesis.

Findings

Heavy Higgs states can be produced at 100 TeV colliders up to 10 TeV mass.

Resonant production in di-jet and top-pair channels is feasible.

Flavor experiments can also probe the same mass range.

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.
