The $F/D$ ratio and meson-baryon couplings from QCD sum rules-II

Hungchong Kim, Takumi Doi, Makoto Oka +1

Using QCD sum rules, we compute the diagonal meson-baryon couplings, $\pi NN$, $\eta NN$, $\pi \Xi \Xi$, $\eta \Xi \Xi$, $\pi \Sigma \Sigma$ and $\eta \Sigma \Sigma$, from the baryon-baryon correlation function with a meson, $i\int d…
