Supersymmetric U (1) Y′ ⊗ U (1) B - L extension of the Standard Model
(2017-06-10)
We build a supersymmetric version with SU(3)C ⊗ SU(2)L ⊗ U(1)Y′⊗ U(1)B-L gauge symmetry, where Y′ is a new charge and B and L are the usual baryonic and leptonic numbers. The model has three right-handed neutrinos with ...
Electroweak precision constraints on the Lee-Wick standard model
(INT SCHOOL ADVANCED STUDIES, 2008)
We perform an analysis of the electroweak precision observables in the Lee-Wick Standard Model. The most stringent restrictions come from the S and T parameters that receive important tree level and one loop contributions. ...
Neutrino predictions from a left-right symmetric flavored extension of the standard model
(2019)
We propose a left-right symmetric electroweak extension of the Standard Model based on the Delta (27) family symmetry. The masses of all electrically charged Standard Model fermions lighter than the top quark are induced ...
