Search for new resonances decaying via WZ to leptons in proton-proton collisions at root s=8TeV

Abstract

A search is performed in proton-proton collisions at root 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 fb -1 . 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
