A General Introduction to the Strong CP Problem
Electroweak (-like) baryogenesis
Electroweak (-like) phase transition is expected to happen in the early universe, given the well-known spontaneous gauge symmetry breaking. This phase transition, if of first order, can provide the necessary out-of-equilbrium condition for baryogenesis. Such a phase transition can happen for the SM electroweak symmetry breaking, or any other similar symmetry breaking in BSM gauge group extensions. This project investigates possibilities to achieve electroweak (-like) baryogenesis in different models.
Electroweak (-like) baryogenesis
Parity-symmetric model
A type of models that can solve the strong CP problem, with large potential to explain the origin of matter-antimatter asymmetry and provide dark matter candidate.

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 …
