N2 - We present a complete calculation of the script O sign(αs) QCD corrections to the width of the decay H+ → tb̄ within the Minimal Supersymmetric Standard Model. We find that the QCD corrections are quite important, and that the supersymmetric QCD corrections (due to gluino, t̃ and b̃ exchange) can be comparable to or even larger than the standard QCD corrections in a large region of the supersymmetric parameter space. This is mainly due to the effect of large left-right mixings of stop (t̃) and sbottom (b̃). This could significantly affect the phenomenology of the H+ search.
