Electroweak Corrections to the Decays of Stop and Gluino

Abstract

The electroweak corrections at the order of $O({\alpha }_{ew}{m}_{t(b)}^2/m_W^2)$ to the partial widths of the ${\tilde{t}}_2\to \tilde{g}+t$ and $\tilde{g}\to {\tilde{t}}_1+\bar{t}$ decays (depending on the masses of the particles involved) are investigated within the Supersymmetric Standard Model. The relative corrections can reach the value of 10% in some parameter space, which can be comparable with the corresponding QCD corrections. Therefore, they should be taken into account for the precise experimental measurement at future colliders.
