Higgs-photon associated production at $e\bar{e}$ colliders

Abstract

We present complete analytical expressions for the amplitudes of the process $e\bar{e}\to H{\hat{I}}^3$. The calculation is performed using nonlinear gauges, which significantly simplifies both the actual analytical calculation and the check of its gauge invariance. After comparing our results with a previous numerical calculation, we extend the range of Higgs masses and center of mass energies to those appropriate to LEP 200 and a future linear collider.
