Description
The value of the b-baryon polarization can be extracted from inclusive data at the CERN e+e- LEP with better than 10% precision based on current statistics. We present a new variable by which to measure the polarization, which is the ratio of the average electron energy to the average neutrino energy. This variable is both sensitive to polarization and insensitive to fragmentation uncertainties
