Axial charges of octet baryons in two-flavor lattice QCD
Erkol, Güray; Oka, M.; Takahashi, T. T. (Elsevier, 2010-03-15)We evaluate the strangeness-conserving NN, ΣΣ, ΞΞ, ΛΣ and the strangeness-changing ΛN, ΣN, ΛΞ, ΣΞ axial charges in lattice QCD with two flavors of dynamical quarks and extend our previous work on pseudoscalar-meson–octet-baryon ... -
Meson-baryon coupling constants in two-flavor lattice QCD
Erkol, Güray; Oka, M.; Takahashi, T. T. (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 ... -
Pseudoscalar-meson octet-baryon coupling constants from two-flavor lattice QCD
Takahashi, T. T.; Erkol, Güray; Oka, M. (Elsevier, 2010-04-01)We evaluate the pseudoscalar-meson octet-baryon coupling constants and the corresponding axial charges in eight channels (πNN, πΣΣ, πΛΣ, KΛN, KΣN, πΞΞ, KΛΞ and KΣΞ) in lattice QCD with two flavors of dynamical quarks. The ... -
Pseudoscalar-meson-octet-baryon coupling constants in two-flavor lattice QCD
Erkol, Güray; Oka, M.; Takahashi, T. T. (American Physical Society, 2009-04-01)We evaluate the πΝΝ, π∑∑, πΛ∑, KΛN and K∑N coupling constants and the corresponding monopole masses in lattice QCD with two flavors of dynamical quarks. The parameters representing the SU(3)-flavor symmetry are computed ...
