Query: Search for physics beyond the standard model in events with a Z boson,
  jets, and missing transverse energy in pp collisions at sqrt(s) = 7 TeV   A search is presented for physics beyond the standard model (BSM) in events
with a Z boson, jets, and missing transverse energy (MET). This signature is
motivated by BSM physics scenarios, including supersymmetry. The study is
performed using a sample of proton-proton collision data collected at sqrt(s) =
7 TeV with the CMS experiment at the LHC, corresponding to an integrated
luminosity of 4.98 inverse femtobarns. The contributions from the dominant
standard model backgrounds are estimated from data using two complementary
strategies, the jet-Z balance technique and a method based on modeling MET with
data control samples. In the absence of evidence for BSM physics, we set limits
on the non-standard-model contributions to event yields in the signal regions
and interpret the results in the context of simplified model spectra.
Additional information is provided to facilitate tests of other BSM physics
models.
