Search for new physics in events with opposite-sign dileptons and missing transverse energy with the CMS experiment

TL;DR

This paper reports a search for new physics signals in events with opposite-sign dileptons and missing energy using CMS data, finding no deviations from the Standard Model and setting limits on supersymmetric models.

Contribution

First search for new physics in dilepton events with missing energy at 7 TeV using CMS data, constraining supersymmetric models.

Findings

No excess events beyond Standard Model predictions

Constraints placed on supersymmetric model parameters

Analysis based on 0.98 fb-1 of data at 7 TeV

Abstract

The results of a search for new physics in events with two opposite-sign isolated electrons or muons, hadronic activity, and missing transverse energy in the final state are presented. The results are based on analysis of a data sample with a corresponding integrated luminosity of 0.98 fb-1 produced in pp collisions at a center-of-mass energy of 7 TeV collected by the CMS experiment at the LHC. No evidence for an event yield beyond Standard-Model expectations is found, and constraints on supersymmetric models are deduced from these observations.
