Light cone QCD sum rules for the $g_{{\Xi }_Q{\Xi }_Q\pi }$ coupling constant

Abstract

For the heavy baryons ${\Xi }_c$ and ${\Xi }_b$ the coupling constants $g_{{\Xi }_c{\Xi }_c\pi }$ and $g_{{\Xi }_b{\Xi }_b\pi }$ are calculated in the framework of light cone QCD sum rules. The most general form of the interpolating field of ${\Xi }_Q$ is used in the calculation.
