摘要：

We show that the spontaneous breaking of intermediate-scale gauge symmetries at scale MI or MGUT) ≫ mW induced by soft supersymmetry-breaking terms μ 1 2, m0, A {reversed tilde equals} O(mW) causes sizable D-term contributions O(mW) to all low-energy scalar masses (squarks, sleptons and higgses) which possess non-vanishing charges under the broken generators. Using this fact one can discriminate, based on the low-energy spectrum, between various popular intermediate-scale or grand-unified gauge groups. We prescribe a corrected procedure for computing large logarithmic corrections to the low-energy potential which includes leading logarithms generally neglected in previous calculations. © 1990.
