Abstract

Using data from 2.9 fb-1 of integrated luminosity collected with the CDF II detector at the Tevatron, we search for resonances decaying into a pair of on-shell gauge bosons, WW or WZ, where one W decays into an electron and a neutrino, and the other boson decays into two jets. We observed no statistical significant excess above the expected standard model background, and we set cross section limits at 95% confidence level on G* (Randall-Sundrum gravitron), Z', and W' bosons. By comparing these limits to theoretical cross sections, mass exclusion regions for the three particles are derived. The mass exclusion regions for Z' and W' are futher evaluated as a function of their gauge coupling strength.
