We study the one-loop radiative corrections to the SU(2)-breaking mass splittings between sfermions in SU(2) doublets in the minimal supersymmetric standard model. At the tree level, the differences of the mass (formula presented) squared of SU(2) doublet sfermions (formula presented) in the first two generations are determined by tan β, and and are universal to sleptons and squarks. The radiative correction, however, breaks this relation. The typical deviation from the universality between sleptons and squarks is within ±0.05 in terms of the “effective cos2β" We also study the SUSY parameter dependence of the deviation. For very heavy sfermions, the relative corrections become large.
