gπΛΣ and gKΣΞ from QCD sum rules


The coupling constants gπΛΣ and gKΣΞ are calculated in the QCD sum rule approach using the three-point function method and taking into account the SU(3) symmetry breaking effects. The pattern of SU(3) breaking appears to be different from that based on SU(3) relations.
