Transverse Lepton Polarization in Polarized W Decays
Shao Liu, Myron Bander
Abstract
Calculations of transverse polarization of leptons in the decay W→ lν with polarized W's are presented. Planned accelerators will produce enough W's for observation of the Standard Model contributions to this polarization. One loop corrections to the polarization are given; these are too small to be seen at presently available W sources. The exchange of Majorons will contribute to these polarizations; these may provide limits on the couplings of these particles to leptons.
