Strategy for detecting b polarization effects

Abstract

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 $Z\text{ra}b\bar{b}$ events, the $b$ polarization effects may be detected without large uncertainties of $b$ fragmentation and ${\Lambda }_b$ decay model.
