Search for the associated production of chargino and neutralino in the final state with three leptons

TL;DR

This paper reports a search for supersymmetric particles, specifically chargino and neutralino, in proton-antiproton collisions, focusing on events with three leptons and missing energy, to identify potential signs of new physics.

Contribution

First search for chargino and neutralino production with three leptons at Tevatron, providing experimental constraints on supersymmetry models.

Findings

No significant excess observed over Standard Model predictions

Set new limits on chargino and neutralino masses

Enhanced understanding of supersymmetry signatures in collider data

Abstract

Supersymmetry, if realized in Nature, predicts the existence of new particles, as chargino and neutralino, which might manifest themselves with peculiar signatures. Three leptons and large missing transverse energy in the event could signal their associated production. We report the latest results of the search performed by the CDF Collaboration in proton-antiproton collisions at Tevatron Run II.
