After the LHC is turning on and accumulating more data, the TeV scale seesaw mechanisms for small neutrino masses are gaining more attention. One of the most popular realization of such mechanisms is the inverse seesaw mechanism. In this scenario, the lepton number is supposed to be explicitly violated at very low energy scale. As a result, it naturally provides neutrino masses at sub-eV scale and its signature can be probed at the LHC. Inverse seesaw mechanisms come in three different ways. Here we restrict our investigation to the inverse type II seesaw case where we implement it into the framework of the 3-3-1 model with right-handed neutrinos. Interestingly, we propose the mechanism which provides small masses to both the standard neutrinos as well as to the right-handed ones. The best signature is the doubly charged scalars which are the sextet. We investigate their production at the LHC through the process σ(ρρ→Ζ*,γ*,Ζ′→Δ++Δ−−) and the signal through four leptons final state decay channel.
I Graduate in Medical Physics at the Universidade Católica de Pernambuco, after this I did my Msc. in Particle Physics at the Federal Universit of Paraíba, my Phd. in Particle Physics at Federal Universit of Paraíba with one year as a visiting researcher fellow at University of Sussex and now I'm a postdoctoral Researcher at Institute of Theoretical Physics-CAS.
