Abstract ： We computed the O(αs ) virtual gluino correction to t → H+ b in the minimal supersymmetric standard model, and investigated the dependence of the process on gluino and squark masses. For some values of masses, the correction implies up to 8% reduction in the partial width relative to the tree-level result. Finally, we compared the correction with quantum colourdynamics and electroweak corrections.
