Neutrino phenomenology in a little higgs model with gauge symmetry $SU(3)_c\otimes SU(4)_L\otimes U(1)_X$

Abstract: We carry out a search for possible mechanisms that explain the smallness of neutrino masses in the context of an anomaly-free Little Higgs model with electroweak gauge symmetry SU (4) L U (1) X. By the introduction of one neutral right-handed neutrino per generation, it is shown that the l...

Introduciendo un neutrino derecho por generación, se muestra que la contribución dominante a la masa de neutrinos livianos es dada a orden de un loop. El modelo da lugar a pequeñas correcciones a la masa del Higgs, las cuales son despreciables en comparación con las contribuciones logarítmicamente divergentes provenientes de los bosones gauge. Adicionalmente no existe supresión sobre los acoples de Yukawa del sector leptónico neutro, proporcionando una respuesta a las masas observadas para los neutrinos sin hacer ajustes sobre los acoples de Yukawa. Las masas de Majorana para el neutrino de quiralidad derecha es suprimida por el cut-off de la teoríaMaestríaapplication/pdfspaUniversidad Nacional de Colombia Sede Medellín Facultad de Ciencias Escuela de FísicaEscuela de FísicaPalacio Cárdenas, Guillermo Alberto (2013) Neutrino phenomenology in a little higgs model with gauge symmetry $SU(3)_c\otimes SU(4)_L\otimes U(1)_X$.
