• Baryon axial form factors
• SU(3)-flavor symmetry
• Lattice QCD

We evaluate the strangeness-conserving NN. Sigma Sigma, Xi Xi, Lambda Sigma and the strangeness-changing Lambda N, Sigma N. Lambda Xi, Sigma Xi axial charges in lattice QCD with two flavors of dynamical quarks and extend Our previous work Oil pseudoscalar-meson-octet-baryon coupling constants so as to Include pi Xi Xi, K Lambda Xi and K Sigma Xi coupling constants.
