Abstract

We give compact and explicit formulae for the corrections of asymmetry measurements on the Z⁰ peak induced by vacuum polarization due to supersymmetric particles. We investigate their magnitudes in realistic minimal models based on supergravity and inspired by the superstring. We find that the corrections to the forward-backward asymmetry are unobservably small, whilst corrections to the left-right polarization asymmetry are observable if particles have masses in the range accessible to LEP 200.
