Running of gauge couplings in the MSSM from a unified value at high energiesleads to a successful prediction of the weak mixing angle. Supersymmetricmodels at the TeV scale may contain further hints of high scale physics, suchas the pattern of superpartner masses when evolved from the TeV scale to a highscale using the renormalization group. This running is traditionally assumed tobe independent of effects in the hidden sector. In this paper we re-examinethis assumption, and conclude that the predictions for scalar masses may dependsensitively on the details of the mechanism of supersymmetry breaking. Weidentify mass relations that persist even when such effects are taken intoaccount.Comment: 14 pages, 3 figures Added reference
