Pseudoscalar-meson--octet-baryon coupling constants in two-flavor lattice QCD

G. Erkol, M. Oka, T. T. Takahashi

We evaluate the $\pi N!N$, $\pi \Sigma \Sigma$, $\pi \Lambda \Sigma$, $K\Lambda N$ and $K\Sigma N$ coupling constants and the corresponding monopole masses in lattice QCD with two flavors of dynamical quarks. The parameters…
