Neutrino Masses and Lepton-Flavor Violation in Supersymmetric Models with lopsided Froggatt-Nielsen charges
Joe Sato, Kazuhiro Tobe
We analyze in detail lepton-flavor violation (LFV) in the charged-lepton sector such as , , and the conversion in nuclei, within the framewor…
Matter profile effect in neutrino factory
T. Ota, J. Sato
We point out that the matter profile effect --- the effect of matter density fluctuation on the baseline --- is very important to estimate the parameters in a neutrino factory with…
Ambiguities of theoretical parameters and CP/T violation in neutrino factories
M. Koike, T. Ota, J. Sato
We study the sensitivity to the CP/T-violation search in the presence of ambiguities of the theoretical parameters. Three generations of neutrinos are considered. The parameters wh…
A Constraint on Yukawa-Coupling Unification from Lepton-Flavor Violating Processes
J. Sato, K. Tobe, T. Yanagida
We present a new constraint on a lepton mixing matrix from lepton-flavor violating (LFV) processes in supersymmetric standard models with massive neutrinos. Here, we assume Yuk…
Low-Energy Predictions of Lopsided Family Charges
J. Sato, T. Yanagida
We consider the Froggatt-Nielsen (FN) mechanism reproducing the observed mass hierarchies and mixing angles for quarks and leptons. The large - mixing suggested from rec…
Neutrino Oscillation and CP Violation
Joe Sato
We reconsider the meaning of observing CP violation in neutrino oscillation.
