Contribution

It introduces a model linking neutrino mass patterns with supersymmetry, emphasizing testable collider signatures consistent with recent neutrino data.

Findings

Equal muon and tau production in neutralino decays

Measurable decay gap as a distinctive signature

Compatibility with SuperKamiokande neutrino results

Abstract

Motivated by the recent SuperKamiokande results on atmospheric neutrinos, we incorporate massive neutrinos, with large angle oscillation between the second and third generations, in a theory with R-parity violating supersymmetry. The general features of such a theory are briefly reviewed. We emphasize its testability through the observation of comparable numbers of muons and taus, produced together with the W-boson, in decays of the lightest neutralino. A distinctly measurable decay gap is another remarkable feature of such a scenario.
