Transverse Polarization beyond the Z Energy at LEP

Abstract

Experimental results on transverse polarization obtained at LEP at a beam energy of 50 GeV are shown. The application of the refined orbit correction procedure known as Harmonic Spin Matching, implemented to compensate the depolarizing effects originating from orbit errors and misalignments of the machine elements, is described. Prospects and plans to improve the transverse polarization level at higher energies to extend the range of application of the direct and precise calibration with resonant depolarization are reported
