  A search is presented for physics beyond the standard model (SM) in final
states with opposite-sign isolated lepton pairs accompanied by hadronic jets
and missing transverse energy. The search is performed using LHC data recorded
with the CMS detector, corresponding to an integrated luminosity of 34 inverse
picobarns. No evidence for an event yield beyond SM expectations is found. An
upper limit on the non-SM contribution to the signal region is deduced from the
results. This limit is interpreted in the context of the constrained minimal
supersymmetric model. Additional information is provided to allow testing the
exclusion of specific models of physics beyond the SM.
