Abstract

We consider spin-momentum correlations between the spin of the bottom baryon Λb and the momenta of its decay products in its inclusive semileptonic decay. We define several polar and azimuthal spin-momentum correlation measures in different event coordinate systems. The values of the spin-momentum correlation measures are calculated up to script O sign(1/mb2) using the standard OPE und HQET methods. Some of the measures turn out to be sufficiently large to make them good candidates for a determination of the polarization of the Λb in e.g. Z decays.
