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