Search for physics beyond the standard model in events with tau leptons, jets, and large transverse momentum imbalance in pp collisions at sqrt(s) = 7 TeV

TL;DR

This paper reports a search for new physics beyond the standard model using events with tau leptons, jets, and missing transverse energy in 7 TeV proton-proton collisions, finding no deviations from standard model predictions.

Contribution

The study provides new limits on gluino masses in supersymmetric models based on CMS data at 7 TeV.

Findings

Observed event counts align with standard model expectations.

Established lower bounds on gluino masses in supersymmetry.

No evidence found for physics beyond the standard model.

Abstract

A search for physics beyond the standard model is performed with events having one or more hadronically decaying tau leptons, highly energetic jets, and large transverse momentum imbalance. The data sample corresponds to an integrated luminosity of 4.98 inverse femtobarns of proton-proton collisions at sqrt(s) = 7 TeV collected with the CMS detector at the LHC in 2011. The number of observed events is consistent with predictions for standard model processes. Lower limits on the mass of the gluino in supersymmetric models are determined.
