We investigated the electroweak corrections from one-loop diagrams involving the third generation (s)quarks to the decay width of the process 1 + → W + 1 0 in the framework of the minimal supersymmetric standard model. Our calculation shows that these corrections are not very sensitive to the mass of the lightest neutralino 1 0 and the sbottom mixing angle θ b , but depend strongly on the top squark mixing angle θ t and tanβ. With our chosen parameters, we find that these radiative corrections can exceed 10%, therefore they should be taken into account for the precise experimental measurement at future colliders.
