Solving the strong CP problem

High Energy Physics - Phenomenology 2025-01-29 v1

Abstract

I briefly review solutions to the strong CP problem based on axions, parity invariance, CP-invariance, and present a new idea based on CP as part of a spontaneously broken flavour symmetry such as a U(1) or modular invariance.
