On the capture rates of big bang neutrinos by nuclei within the Dirac and Majorana hypotheses
(IOP Publishing, 2018-10)
The capture rates of non-relativistic neutrinos on beta decaying nuclei depends on whether their mass is Dirac or Majorana. It is known that for relic neutrinos from the big-bang, and within minimal assumptions, the rate ...
Higgs sector from a non-universal U(1)x supersymmetric model
(Universidad Nacional de ColombiaBogotá - Ciencias - Maestría en Ciencias - FísicaDepartamento de FísicaFacultad de CienciasBogotá, ColombiaUniversidad Nacional de Colombia - Sede Bogotá, 2021-05-11)
The project consider a U(1)x non-universal extension to the Minimal Supersymetric Standard Model for explaining more naturally the fermion mass hierarchy, in the sense that Yukawa couplings with the scalar background are ...
