Search for Supersymmetry in p\overline{p} Collisions at \sqrt{s} =1.96 TeV Using the Trilepton Signature of Chargino-Neutralino Production

TL;DR

This paper reports a search for supersymmetry at the Tevatron collider by analyzing three-lepton signatures from chargino-neutralino production, providing experimental limits within the mSugra model.

Contribution

First search for SUSY via chargino-neutralino trilepton signature at Tevatron using CDF II data within the mSugra framework.

Findings

No significant excess observed over Standard Model predictions.

Set limits on chargino and neutralino masses in the mSugra model.

Improved constraints on SUSY parameter space.

Abstract

The production of chargino-neutralino pairs and their subsequent leptonic decays is one of the most promising supersymmetry (SUSY) signatures at the Tevatron $p\bar{p}$ collider. We present here the most recent results on the search for the three-lepton and missing-transverse-energy SUSY signature using data collected with the CDF II detector. The results are interpreted within the minimal supergravity (mSugra) scenario.
