Probing new gauge-boson couplings via three-body decays
We examine the possibility of using rare, three-body decays of a new neutral gauge boson ${Z}_{2}$ to probe its gauge couplings at hadron colliders. Specifically, we study the decays ${Z}_{2}\ensuremath{\rightarrow}\mathrm{Wl}\ensuremath{\nu}$ and ${Z}_{2}\ensuremath{\rightarrow}Z\ensuremath{\nu}\overline{\ensuremath{\nu}}$ and find that much knowledge of the ${Z}_{2}$ properties can be obtained from these processes. In particular, these …
