  A search is performed in proton-proton collisions at sqrt(s) = 8 TeV for
exotic particles decaying via WZ to fully leptonic final states with electrons,
muons, and neutrinos. The data set corresponds to an integrated luminosity of
19.5 inverse femtobarns. No significant excess is observed above the expected
standard model background. Upper bounds at 95% confidence level are set on the
production cross section of a W' boson as predicted by an extended gauge model,
and on the W'WZ coupling. The expected and observed mass limits for a W' boson,
as predicted by this model, are 1.55 and 1.47 TeV, respectively. Stringent
limits are also set in the context of low-scale technicolor models under a
range of assumptions for the model parameters.
