Meson-baryon coupling constants in two-flavor lattice QCD
(American Institute of Physics, 2010)We evaluate the pseudoscalar-meson coupling constants and the strangeness-conservingand the strangeness-changing axial charges of octet baryons in lattice QCD with two flavors ofdynamical quarks.We find that the coupling ... -
QCD sum rules for the coupling constants of vector mesons to octet baryons
(Springer Science+Business Media, 2013-05)The QCD sum rules on the light cone proposed by Wang for the coupling constants of the ρ meson are generalized to the vector mesons ω and φ and all octet baryons, the Λ-hyperon included. A comparison with other results is given.
