Description
Virtual contributions of squark-gluino coupling to the top quark decay width Γ(t→W+b) and Γ(t→H+b) are calculated to one-loop order in the minimal supersymmetric standard model. The corrections are found to reduce the top quark width. If the squarks and gluinos take their lowest allowed masses, the correction to Γ(t→W+b) can reach the level of 1% and the correction to Γ(t→H+b) is typically a few percent
