Nelson-Barr Models with Vector-Like Quark Doublets
G. H. S. Alves, C. C. Nishi, L. Vecchi
We investigate Nelson--Barr solutions to the strong CP problem in which spontaneous CP violation is transmitted to the Standard Model through mixing with a vector-like partner of t…

Seesaw Limit of the Nelson-Barr Mechanism
A. L. Cherchiglia, A. G. Dias, J. Leite +1
We investigate how the solution to the strong CP problem and the explanation for the observed fermion mass hierarchies can be intrinsically related. Specifically, we explore the Ne…
