Testing the handedness of a heavy $W^{\prime }$ at future hadron colliders

Abstract

We show that the associated production $pp\to W^{\prime }W$, and the rare decay $pp\to W^{\prime }\to \bar{\ell }\ell W$ are useful tests of $W^{\prime }$ couplings to fermions at future hadron colliders. For $M_{W^{\prime }}\sim (1-3)$ TeV they would allow a clean determination on whether the $W^{\prime }$ couples to $V-A$ or $V+A$ currents. As an illustration a model in which the $W^{\prime \pm }$ couples only to $V-A$ currents is contrasted to the left-right symmetric models which involve $V+A$ currents.
