Determination of the strong vertices of doubly heavy baryons with pseudoscalar mesons in QCD

Abstract

The strong coupling constant of doubly heavy baryons with light pseudoscalar mesons $\pi$ and $K$ are computed within the light cone sum rules. We take into account two-particle and three-particle distribution amplitudes of the said pseudoscalar mesons. We compare our result with the one existing in the literature.
