Lambda hyperon as helicity analyzer of s quark in B decay

High Energy Physics - Phenomenology 2009-11-07 v1

Abstract

We explore how well one can probe the s quark chirality of the fundamental weak interaction of nonleptonic B decay using the spin-analyzing property of the Lambda 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 the decay B-bar to Lambda X.
