Search for new physics with same-sign isolated dilepton events with jets and missing transverse energy at the LHC

TL;DR

This study searches for signs of new physics in LHC collision data with same-sign dileptons, jets, and missing energy, finding no deviations from the standard model predictions.

Contribution

First CMS analysis using 7 TeV data to search for new physics in same-sign dilepton events with detailed event selection and efficiency information.

Findings

No excess of events observed beyond standard model expectations.

Results set constraints on new physics models.

Data and analysis details provided for broader interpretation.

Abstract

The results of searches for new physics in events with two same-sign isolated leptons, hadronic jets, and missing transverse energy in the final state are presented. The searches use an integrated luminosity of 35 inverse picobarns of pp collision data at a centre-of-mass energy of 7 TeV collected by the CMS experiment at the LHC. The observed numbers of events agree with the standard model predictions, and no evidence for new physics is found. To facilitate the interpretation of our data in a broader range of new physics scenarios, information on our event selection, detector response, and efficiencies is provided.
