Neutrino oscillations from supersymmetry without R-parity—its implications on the flavor structure of the theory

We discuss here some flavor structure aspects of the complete theory of supersymmetry without R-parity addressed from the perspective of fitting neutrino oscillation data based on the recent Super-Kamiokande result. The single-VEV parameterization of supersymmetry without R-parity is first reviewed, illustrating some important features not generally appreciated. For the flavor structure discussions, a naive, flavor-model-independent, analysis is presented, from which a few interesting things can be learned.
