The neutrino sector

We consider a renormalizable theory, which successfully explains the number of Standard Model (SM) fermion families and whose non-SM scalar sector includes an axion dark matter as well as a field responsible for cosmological inflation. In such theory, the axion gets its mass via radiative corrections at one-loop level mediated by virtual top quark, right handed Majorana neutrinos and SM gauge bosons.

The thesis proposes a class for the new economic 3-3-1 model, called a simple 3-3-1 model, in order to address the mentioned problems. The simple 3-3-1 model considers the simplest lepton sector and the scalar sector. This setting leads to natural components of the inert fields such as scalar inert fields and right-handed neutrino.

In this paper, we study the combined sensitivity of T2K-II and NOvA, the world leading long-baseline neutrino oscillation experiments, to CP violation in lepton sector. By operating until the year 2026, T2K-II is expected to collect a total exposure of 20×1021 protons-on-target. Meanwhile, NOνA experiment has a plan to extend its run up to 2024 for accumulating totally an amount of 72 × 1020 protons-on-target.

The exact solution for neutrino mass matrix of the Zee-Babu model is derived. The tribimaximal mixing imposes the conditions on the Yukawa couplings, from which the normal mass hierarchy is preferred. The derived conditions give a possibility of maximal CP violation in the neutrino sector.

At present, particle physics faces problems related with disparity in diphoton decay of Higgs boson, discrepancy between theory and experiment of about 3.6σ in anomalous magnetic moment of the muon and neutrino physics. Moreover, the existence of Dark Matter and the Matter-Antimatter Asymmetry are challenges for any physical model. In this review I present some solutions in the framework of the 3-3-1 models. The simple (by Higgs sector) models contain the hybrid inflationary scenario and the first-order phase transitions, from which leptogenesis needed for BAU is followed.
