Signatures of Extended Gauge Sectors in $e^+e^-\to \nu\bar\nu\gamma$

Abstract

The ability of high energy $e^+e^-$ colliders to indirectly probe the existence of heavy new charged gauge bosons via their exchange in the reaction $e^+e^-\to \nu\bar\nu\gamma$ is investigated. It is shown that examination of the resulting photon energy spectrum with polarized beams can extend the $W'$ search reach above the center of mass energy.
