Aligned Zee-Grimus-Neufeld model for
R. E. A. Bringas, A. L. Cherchiglia, G. De Conto +1
The recent result of the Fermilab Muon g-2 experiment is still in conflict with the SM prediction if dispersive methods are used as input for the hadronic vacuum polarization. We s…

Effective description of Nelson-Barr models and the theta parameter
Gustavo H. S. Alves, Celso C. Nishi
Nelson-Barr theories solve the strong CP problem with CP spontaneously broken at Î_{CP} and transmitted to the CP conserving version of the SM through vector-like quarks (VLQs). F…

Flavor invariants for the SM with one singlet vector-like quark
E. L. F. de Lima, C. C. Nishi
We study the flavor invariants of the SM augmented by one singlet vector-like quark. Aided by the Hilbert series, we construct all the basic invariants with which any flavor invari…
