## Spin-momentum correlations in inclusive semileptonic decays of polarized $\Lambda_b$ baryons

### Abstract

We consider spin-momentum correlations between the spin of the bottom baryon 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 ${\cal O}(1/m_b^2)$ 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 $\Lambda_b$ in e.g. Z decays
