Phenomenology of the type-II seesaw mechanism
(BrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM FÍSICA, 2019-11-29)
Search for a new heavy scalar particle decaying into a Higgs boson and a new scalar singlet in final states with one or two light leptons and a pair of τ-leptons with the ATLAS detector
(2023)
A search for a new heavy scalar particle X decaying into a Standard Model (SM) Higgs boson and a new singlet scalar particle S is presented. The search uses a protonproton (pp) collision data sample with an integrated ...
Lepton masses and mixing and lepton number violating processes in the minimal 3-3-1 model
(Iop Publishing Ltd, 2017-01-01)
We consider the minimal 3-3-1 model with sterile neutrinos transforming as singlet under the SU(3)(L) circle times U(1)(X) symmetry and we find numerical solutions for these matrices by imposing that besides the observed ...
Scotogenic neutrino masses with gauged matter parity and gauge coupling unification
(Springer Science and Business Media Deutschland GmbH, 2022-03)
Building up on previous work we propose a Dark Matter (DM) model with gauged matter parity and dynamical gauge coupling unification, driven by the same physics responsible for scotogenic neutrino mass generation. Our ...
