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…

Leptonic CP violation from a vector-like lepton

A. L. Cherchiglia, G. De Conto, C. C. Nishi

Leptonic CP violation is yet to be confirmed as an additional source of CP violation in fundamental interactions. We study the case where leptonic CP violation is spontaneous and i…

Flavor constraints for a Vector-like quark of Nelson-Barr type

A. L. Cherchiglia, G. De Conto, C. C. Nishi

The Nelson-Barr (NB) mechanism to solve the strong CP problem assumes CP conservation, arranges vanishing at tree-level and requires vector-like quarks (VLQs) to transmit t…

The Higgs boson in the minimal 3-3-1 model

G. De Conto, A. C. B. Machado, J. P. B. C. de Melo

In this paper we present the mass matrices and mass eigenstates for the CP-even neutral scalars in the minimal 331 model (m331) and its self-interactions, showing that the m331 aut…

Neutron electric dipole moment in the minimal 3-3-1 model

G. De Conto, V. Pleitez

We calculate the electric dipole moment (EDM) for the neutron in the framework of the minimal 3-3-1 model. We assume that the only source of violation arises from a complex tr…

Electron and muon anomalous magnetic dipole moment in a 3-3-1 model

G. De Conto, V. Pleitez

We calculate, in the context of a 3-3-1 model with heavy charged leptons, constraints on some parameters of the extra particles in the model by imposing that their contributions to…
