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…
Brazilian Report on Dark Matter 2024
I. F. M. Albuquerque, J. Alcaniz, A. Alves +51
One of the key scientific objectives for the next decade is to uncover the nature of dark matter (DM). We should continue prioritizing targets such as weakly-interacting massive pa…
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…
Leptonic CP violation from the seesaw
C. C. Nishi, J. I. Silva-Marcos
The seesaw extension of the SM explains the tiny neutrino masses and it is accompanied by many CP violating phases. We study the case where all leptonic CP violation arises from th…
Explicit parametrization of more than one vector-like quark of Nelson-Barr type
G. H. S. Alves, A. L. Cherchiglia, C. C. Nishi
Nelson-Barr models solve the strong CP problem based on spontaneous CP violation and generically requires vector-like quarks (VLQs) mixing with standard quarks to transmit the CP v…
Connecting to neutrino mass in the extended neutrinophilic 2HDM
A. L. Cherchiglia, G. De Conto, C. C. Nishi
One simple way to lower the scale of the seesaw mechanism that generates neutrino masses is to attribute part of their smallness to a suppressed vacuum expectation value of a secon…
