Fermion mass hierarchy from nonuniversal abelian extensions of the Standard Model

The fermion mass hierarchy is addresed from the framework of an abelian extension of the Standard Model U(1)X. By taking into account the cancellation of chiral anomalies, a set of U(1)X charges is presented with extended scalar and fermionic sectors. The scalar potential is shown, together with the...

Teniendo en cuenta la cancelación de anomalías quirales, un conjunto de cargas de U(1) es presentada con sectores escalares y fermiónicos extendidos. Se muestra el potencial escalar junto con el espectro escalar del modelo, el cual incluye los respectivos bosones de Goldstone, escalares físicos cargados y neutros a escala de TeV y el bosón de Higgs de 125 GeV. Después, la adquisición de masas en el sector de fermiones es estudiado en detalle. Las matrices de masa presentan una textura específica llamada textura de cuadros de supresión, la cual sugiere la jerarquía de masas cuando son diagonalizadas por métodos tanto algebraicos como numéricos. El modelo resulta ser consistente a 5sigma y 3sigma en los sectores de quarks y leptones, respectivamente, sin necesidad de usar ajustes finos indeseados.Maestríaapplication/pdfspaUniversidad Nacional de Colombia Sede Bogotá Facultad de Ciencias Departamento de FísicaDepartamento de FísicaMantilla Serrano, Sebastian Felipe (2017) Fermion mass hierarchy from nonuniversal abelian extensions of the Standard Model.
