* OPTIMIZATION OF TRANSVERSE SPIN-POLARIZATION IN THE LEP STORAGE
RING AND ITS USE FOR PRECISION MEASUREMENTS OF THE Z-BOSON.
It is shown how the beam polarization in LEP was increased from 15% to 57% and how it was used for accurate measurements of the LEP beam energy. The resulting errors on the mass and the decay width of the Z-boson are discussed. Unfortunately had to be in German.
