Abstract
We study possible new physics interactions in the ZZH vertex contributing to the Higgsstrahlung process \(e^+ e^- \rightarrow ZH\) at proposed future \(e^+e^-\) colliders using the polarization of the Z as a probe. We estimate the limits on the anomalous couplings using the angular asymmetries of charged leptons from Z decay which are simply related to the Z polarization asymmetries at centre of mass energies of 250 and 500 GeV and various combinations of polarized \(e^+\) and \(e^-\) beams.
