Abstract

We present the first search for an electrically charged resonance W decaying to a WZ boson pair using 4.1fb1 of integrated luminosity collected with the D0 detector at the Fermilab Tevatron pp¯ collider. The WZ pairs are reconstructed through their decays into three charged leptons (=e, μ). A total of 9 data events is observed in good agreement with the background prediction. We set 95% C.L. limits on the WWZ coupling and on the W production cross section multiplied by the branching fractions. We also exclude W masses between 188 and 520 GeV within a simple extension of the standard model and set the most restrictive limits to date on low-scale technicolor models.
