Tevatron Signatures of an R-parity Violating Supersymmetric Theory

TL;DR

This paper proposes that R-parity violating supersymmetry, explaining neutrino oscillations, predicts distinctive like-sign dimuon and ditau signals at the Tevatron, which can be used to test the theory and reconstruct the neutralino.

Contribution

It introduces a testable supersymmetric scenario linking neutrino masses with collider signatures, enabling neutralino reconstruction at the Tevatron.

Findings

Like-sign dimuon and ditau signals with substantial rates

Separation of signals from standard model backgrounds

Potential for complete neutralino reconstruction

Abstract

We show that an R-parity violating supersymmetric scenario which can account for the atmospheric nu(mu) deficit has testable signals at the Fermilab Tevatron with upgraded energy and luminosity. The explanation of neutrino masses and maximal nu(mu)-nu(tau) oscillation in terms of bilinear R-violating terms in the superpotential associates comparable numbers of muons and tau's resulting from decays of the lightest neutralino. We show that this should lead to like-sign dimuons and ditaus with substantial rates, in a form that separates them from standard model backgrounds and other signals of supersymmetry. One here also has the possibility of completely reconstructing the lightest neutralino.
