Hyperon-nucleon coupling from QCD sum rules

Description

The NKY coupling constant for Y = Λ and σ is evaluated in a QCD sum rule calculation. We discuss and extend the result of a previous analysis in the □iγ5 structure and compare it with the result obtained with the use of the γ5σμν structure. We find a huge violation of the SU(3) symmetry in the γ5σμν structure
