Parity-symmetric model

Jul 5, 2023

Introduction

Parity is a good solution to the strong CP problem. I have written a post for strong CP problem and its solutions. Basically, we can have a gauge group of the standard parity-symmetric model $SU(3)_C \times SU(2)_L \times SU(2)_R \times U(1)_{B-L}$. The next step is: can this model provide us more solutions to other unsolved puzzles?

Recently, I’ve been working in this direction. Things included are: dark matter, baryogenesis, and neutrino masses.

Baryogenesis in a parity solution to the strong CP problem
Space-time parity has been proposed as a solution to the strong CP problem for decades. However, electroweak (-like) baryogenesis from the $SU(2)_R \times U(1)_X \to U(1)_Y$ phase transition has been regarded as difficult. This paper investigates the possibility to realize the electroweak (-like) phase transition in such a phase transition, and discuss the resulting cosmological results.
