2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/46211We study the 1-loop corrections to the charged Higgs production both in the Minimal Supersymmetric Standard Model (MSSM) and in a more general type II two-Higgs-doublet model (THDM-II). We consider the full set of corrections (including soft photon contributions as well as box diagrams), and define a parametrization that allows a comparison between the two models. Besides the soft photon radiation there can be prominent model-dependent effects.Latex, 7 pages, 2 figures uuencoded, to appear in Proceedings of the Physics with $e^+e^-$ Linear Colliders Workshop, Annecy -- Gran Sasso -- Hamburg 1995, ed.
