Description
We explore how well one can probe the s quark chirality of the fundamental weak interaction of nonleptonic B decay using the spin-analysing property of the Λ hyperon. We present the prediction of the standard model as quantitatively as possible in a perturbative QCD picture avoiding detailed form-factor calculation involving quark mass corrections. A clean test of chirality will be possible with B-bar → ΛX when X is an antibaryon or its excited state. (brief report)
