Query: Search for a W' or techni-rho decaying into WZ in pp collisions at
  sqrt(s) = 7 TeV   A search is performed in pp collisions at sqrt(s) = 7 TeV for exotic
particles decaying via WZ to final states with electrons and muons. The data
sample corresponds to an integrated luminosity of approximately 5 inverse
femtobarns. No significant excess is observed in the data above the expected
standard model background. Upper bounds at 95% confidence level are set on the
production cross section of the W' boson described by the sequential standard
model and on the W'WZ coupling. W' bosons with masses below 1143 GeV are
excluded. Limits are also set in the context of low-scale technicolor models,
under a range of assumptions concerning the model parameters.
