Spin Content of Lambda in QCD Sum Rules
G. Erkol, M. Oka
We calculate the isoscalar axial-vector coupling constants of the Lambda hyperon using the method of QCD sum rules. A determination of these coupling constants reveals the individu…

Pseudoscalar-meson--octet-baryon coupling constants in two-flavor lattice QCD
G. Erkol, M. Oka, T. T. Takahashi
We evaluate the , , , and coupling constants and the corresponding monopole masses in lattice QCD with two flavors of dynamical quarks. The parameters…
