Neutrino Mass Matrix in the Minimal Supergravity Model: Bi-large Mixing with Trilinear R-parity Violation
Eung Jin Chun, Dong-Won Jung, Sin Kyu Kang +1
We study the correlation between the neutrino oscillation and the production/decay of the lightest supersymmetric particle(LSP) in the context of the minimal supergravity model(mSU…
Wrong-sign Kaons in B decays and New Physics
Eung Jin Chun, Jae Sik Lee
New physics can possibly emerge in the B decays into wrong-sign kaons for which the standard model contributions are extremely suppressed. We analyze two-body decays of …
Radiative Splitting of Three Degenerate Neutrinos
Eung Jin Chun, Sin Kyu Kang
We propose a radiative origin of the two mass splittings of three degenerate Majorana neutrinos. It can be achieved by extending the standard model to have the usual effective dime…
Flatons and Peccei-Quinn Symmetry
E. J. Chun, D. Comelli, David H. Lyth
We study in detail a supersymmetric Peccei-Quinn model, which has a DFSZ and a KSVZ version. The fields breaking the Peccei-Quinn (PQ) symmetry correspond to flat directions (flato…
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…
