Search for New Resonances Decaying Via WZ to Leptons in Proton-Proton Collisions at Square Root s=8TeV.

摘要

A search is performed in proton-proton collisions at square 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(sub -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(sub 1) boson as predicted by an extended gauge model, and on the W(sub 1)WZ coupling. The expected and observed mass limits for a W(sub 1) boson, as predicted by this model, are 1.55 and 1.47 TeV, respectively. Stringent limits are also set in the context of los-scale technicolor models under a range of assumptions for the model parameters.
