## Abstract

We study the decays of the charged Higgs boson H^+ within the Minimal Supersymmetric Standard Model. We find that the supersymetric mode 'stop + sbottom-bar' can dominate the H^+ decays in a wide range of the model parameters due to the large Yukawa couplings and mixings of stop and sbottom. Compared to the conventional modes 'tau^+ nu' and 't b-bar', this mode has very distinctive signatures. This could have a decisive impact on H^+ searches at future colliders. We find also that the QCD corrections to the 'stop + sbottom-bar' mode are significant, but that they do not invalidate our tree-level conclusion above.

## Recorded benchmark results

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.
