Abstract
Results on first experimental evidence of transverse polarization in LEP at E = 46.5 GeV (ν s = 105.55) are reported. The polarization level associated to the significant asymmetry observed in the Compton back-scattered photon distribution when illuminating the electron beam with circularly polarized laser light is estimated to be 9% ± 2% (systematic) ±2% (statistical). The validity of the polarization signal was assessed by exciting a depolarizing resonance. The measurement is consistent with the predicted polarization degree with the especially prepared polarization optics.
