Light cone QCD sum rules study of the semileptonic heavy ${\Xi }_Q$ and ${\Xi }_Q^{\prime }$ transitions to $\Xi$ and $\Sigma$ baryons

Abstract

The semileptonic decays of heavy spin--1/2, ${\Xi }_{b(c)}$ and ${\Xi }_{b(c)}^{\prime }$ baryons to the light spin-- 1/2, $\Xi$ and $\Sigma$ baryons are investigated in the framework of the light cone QCD sum rules. In particular, using the most general form of the interpolating currents for the heavy baryons as well as the distribution amplitudes of the $\Xi$ and $\Sigma$ baryons, we calculate all form factors entering the matrix elements of the corresponding effective Hamiltonians in full QCD. Having calculated the responsible form factors, we evaluate the decay rates and branching fractions of the related transitions.
