ALP-assisted strong first-order electroweak phase transition and baryogenesis
The coupling between an axion-like particle (ALP) and the Higgs boson can potentially enhance the electroweak phase transition to be strongly first order. Local electroweak baryogensis, which has been ruled out for the traditioanl Higgs operator, can be effective for the operator that couples the ALP with various anomalies. This paper investigates such a scenario with various ways to probe.

Baryogenesis in a parity solution to the strong CP problem
Space-time parity can solve the strong CP problem and introduces a spontaneously broken $SU(2)_R$ gauge symmetry. We investigate the …

Electroweak-like baryogenesis with new chiral matter
We propose a framework where a phase transition associated with a gauge symmetry breaking that occurs (not far) above the electroweak …
