Extension of SUSY SU(5) GUTs with Nelson-Barr models

Year: 2025

Type: article

Abstract: A bstract In this paper we extend the supersymmetric SU(5) GUTs with the Nelson-Barr (NB) models. The NB models are a candidate for the solution of the strong CP problem. We show that the parameters in the CKM matrix are reproduced while the mass ratios of the down-type quarks and leptons in the second and third generations are explained in the minimal extension.
