$ZγH$ Vertex Effects at Future Colliders

Abstract

We show that the Higgs production in $eγ$ collisions, through the one-loop reaction $eγ\to eH$ at large transverse momentum, can provide a precise determination of the $ZγH$ vertex. We concentrate on the analysis of signal rates vs background looking for strategies to improve the ratio $S/B$. Possible bounds on anomalous contributions to the $ZγH$ vertex are derived.
