Abstract
We study the O(\ensuremath{\alpha}${\mathit{m}}_{\mathit{t}}^{2}$/${\mathit{m}}_{\mathit{W}}^{2}$) Yukawa corrections to the process ${\mathit{e}}^{+}$${\mathit{e}}^{\mathrm{\ensuremath{-}}}$\ensuremath{\rightarrow}\ensuremath{\gamma}\ensuremath{\gamma}\ensuremath{\rightarrow}${\mathit{H}}^{+}$${\mathit{H}}^{\mathrm{\ensuremath{-}}}$ at the Next Linear Collider. The analyses of the production rate are made in the framework of the two-Higgs-doublet model for possible parameter values of the Higgs sector. We find that the corrections imply a few to 22% reduction in the production cross section in ${\mathit{e}}^{+}$${\mathit{e}}^{\mathrm{\ensuremath{-}}}$ colliders. \textcopyright{} 1996 The American Physical Society.
