Inclusive Search for Squarks and Gluinos Production at CDF

TL;DR

This paper reports a search for squarks and gluinos in proton-antiproton collisions at the Tevatron, finding no evidence of new particles and setting new mass limits within the minimal supergravity framework.

Contribution

First search for squarks and gluinos at Tevatron with 1.1 fb-1 data, providing new mass limits under R-parity conservation assumptions.

Findings

No excess events observed over Standard Model predictions.

New lower mass limits set for gluinos and squarks.

Results constrain supersymmetric models.

Abstract

We present preliminary results on a search for squarks and gluinos in proton-antiproton collisions with a center-of-mass energy of 1.96 TeV and based on 1.1 fb-1 of data collected by the CDF detector in the Tevatron Run II. Events with multiple jets of hadrons and large missing transverse energy in the final state are studied within the framework of minimal supergravity and assuming R-parity conservation. No excess with respect to Standard Model predictions is observed and new limits on the gluino and squark masses are extracted.
