Bi-maximal neutrino mixing and small U_{e3} from Abelian flavor symmetry
Kiwoon Choi, Eung Jin Chun, Kyuwan Hwang +1
Atmospheric neutrino data strongly suggests a near-maximal ν_μ-ν_τ mixing and also solar neutrino data can be nicely explained by another near-maximal ν_e-ν_μ or ν_e-ν_τ mixing. We…
CP Violation, Sneutrino Oscillation and Neutrino Masses in R-parity Violating Supersymmetric Standard Model
Eung Jin Chun
In supersymmetric theories, sneutrino--anti-sneutrino mixing can occur with the oscillation time ps corresponding the atmospheric neutrino mass scale eV. We…
Lepton Flavor Violation and Radiative Neutrino Masses
Eung Jin Chun
Lepton flavor violation in various sectors of the theory can bring important effects on neutrino masses and mixing through wave function renormalization. We examine general conditi…
Axino as a sterile neutrino and R parity violation
Kiwoon Choi, Eung Jin Chun, Kyuwan Hwang
We point out that axino can be a natural candidate for sterile neutrino which would accommodate the LSND data with atmospheric and solar neutrino oscillations. It is shown that the…
