Abstract

We study the discovery potential of Z branching ratios due to contributions induced by the minimal supersymmetric standard model (MSSM) electroweak sector, assuming that the squarks and gluinos are heavy. Precision measurements at a future Z factory would yield sensitivity to MSSM that is complementary to direct searches at the LHC, provided that the systematic uncertainties can be reduced to a level comparable to the expected statistical uncertainties.
