摘要

We suggest a strategy for detecting $b$ polarization effects in $e^+e^-$ annihilation on $Z$ resonance. Using two types of inclusive leptonic samples with different ${\Lambda_b}$ fractions in $Z \ra b\bar{b}$ events, the $b$ polarization effects may be detected without large uncertainties of $b$ fragmentation and ${\Lambda_b}$ decay model.
