Neutrino Oscillations and R-parity Violating Collider Signals

TL;DR

This paper explores how R-parity violating supersymmetry models, which explain neutrino oscillations, can be tested at colliders by analyzing decay products of the neutralino LSP, linking collider signals to neutrino physics.

Contribution

It systematically examines neutralino decay processes in R-parity violating MSSM, demonstrating collider tests for neutrino oscillation models.

Findings

Collider signals can probe neutrino oscillations in most MSSM parameter space.

Neutralino decay patterns are directly linked to neutrino mass generation mechanisms.

The study provides a framework to connect collider observations with neutrino physics.

Abstract

R-parity and L violation in the MSSM would be the origin of the neutrino oscillation observed in Super-Kamiokande. A distinctive feature of this framework is that it can be tested in colliders by observing decay products of the destabilized LSP. We examine all the possible decay processes of the neutralino LSP assuming the bilinear contribution to neutrino masses dominates over the trilinear one which gives rise to the solar neutrino mass. We find that it is possible to probe neutrino oscillations through colliders in most of the R-parity conserving MSSM parameter space.
