Abstract

We study radiative corrections to third generation scalar fermions into gauge bosons ZZ and W±W^\pm. We include both SUSY-QCD, QED and full electroweak corrections. It is found that the electroweak corrections can be of the same order as the SUSY-QCD corrections and interfere destructively in some region of parameter space. The full one loop correction can reach 10% in some SUGRA scenario, while in general MSSM, the one loop correction can reach 20% for large tanβ\tan\beta and large trilinear soft breaking terms AbA_b.
