Top quark loop corrections to the decay $H^{+}\to h^0{W}^{+}$ in the Two Higgs Doublet Model

Abstract

We calculate the decay width for the process $H^{+}\to h^0{W}^{+}$ up to order $g^4$ in the framework of the Two Higgs Doublet Model. We argue that for some reasonable choice of the free parameters the contribution from the one-loop graphs can be as large as 40%.
