Light Singlet Fermions and Neutrino Physics
E. J. Chun, A. S. Yoshipura, A. Yu. Smirnov
The existence of a light singlet fermion mixed with the electron neutrino is hinted by the simultaneous explanation of various neutrino anomalies. We show that supersymmetry can pr…
Gauged R-symmetry, Fermion and Higgs Mass Problem
Eung Jin Chun
We consider the simplest model of gauge symmetry with one extra singlet field whose vacuum expectation value breaks the horizontal…
Quasi Goldstone Fermion As a Sterile Neutrino
E. J. Chun, A. S. Joshipura, A. Yu. Smirnov
The existence of sterile neutrino is hinted by simultaneous explanation of diverse neutrino anomalies. We suggest that the quasi Goldstone fermions (QGF) arising in supersymmetric…
Models of Light Singlet Fermion and Neutrino Phenomenology
E. J. Chun, Anjan S. Joshipura, A. Yu. Smirnov
We suggest that a singlet fermion exists beyond the standard see-saw structure. It mixes with light neutrinos via interactions with the right-handed neutrino components, so tha…
