Constraining Selectron LSP Scenarios with Tevatron Trilepton Searches

TL;DR

This paper uses Tevatron trilepton search results to set bounds on R-parity violating supersymmetric models with a selectron as the lightest superpartner, excluding certain parameter spaces and predicting future testability up to 170 GeV.

Contribution

It provides the first comprehensive constraints on selectron LSP scenarios using Tevatron data within lepton number violating supergravity models.

Findings

Complete parameter space consistent with muon g-2 can be excluded at 90% CL.

Tevatron can test selectron LSP masses up to 170 GeV with 10 fb^{-1} data.

No excess events above Standard Model predictions were observed.

Abstract

The Tevatron collaborations have searched for associated production of charginos and neutralinos via trilepton final states. No events above the Standard Model prediction were observed. We employ these results to put stringent bounds on R-parity violating models with a right-handed scalar electron as the lightest supersymmetric particle. We work in the framework of lepton number violating minimal supergravity. We find that within these models the complete parameter space consistent with the anomalous magnetic moment of the muon can be excluded at 90% confidence level. We also give prospects for Tevatron trilepton searches assuming an integrated luminosity of 10 fb^{-1}. We find that Tevatron will be able to test selectron LSP masses up to 170 GeV.
