Pseudoscalar-meson--octet-baryon coupling constants in two-flavor lattice QCD [PDF]
, 2008 We evaluate the pseudoscalar-meson octet-baryon coupling constants and the corresponding axial charges in eight channels ( πNN , π ΣΣ, π ΛΣ, K Λ N , K Σ N , π ΞΞ, K ΛΞ and K ΣΞ) in lattice QCD with two flavors of dynamical quarks. The parameter α ≡ F / (

B0 and Bs0 decays into J/ψ f0(980) and J/ψ f0(500) and the nature of the scalar resonances
Physics Letters B, 2014 We describe the B0 and Bs0 decays into J/ψ f0(500) and J/ψ f0(980) by taking into account the dominant process for the weak decay of B0 and Bs0 into J/ψ and a qq¯ component.

Determination of light quark masses from the electromagnetic splitting of pseudoscalar meson masses computed with two flavors of domain wall fermions [PDF]
, 2007 We determine the light quark masses from lattice QCD simulations incorporating the electromagnetic interaction of valence quarks, using the splittings of charged and neutral pseudoscalar meson masses as inputs.

Weak decays of $$B_c$$ Bc into two hadrons under flavor SU(3) symmetry
European Physical Journal C: Particles and Fields, 2018 A large number of $$B_c$$ Bc meson events have been recorded at the LHCb detector, especially some two-body hadronic decay modes. We analyzed the weak decays of the $$B_c$$ Bc meson into two hadron states under the flavor SU(3) symmetry.

Pseudoscalar Mesons Scattering off D*-mesons with Chiral Perturbation Theory
EPJ Web of Conferences, 2012 We have systematically calculated the s-wave pseudoscalar mesons and D*- mesons scattering lengths to the third order with chiral perturbation theory, which will be helpful to reveal their strong interaction.

Quark Diagram Analysis of Bottom Meson Emitting Two Pseudoscalar Mesons [PDF]
arXiv, 2009 We investigate decay modes of B mesons emitting two pseudoscalar (P) mesons in the Quark Diagram Scheme at SU(3) level. Several relations among the decay amplitudes are obtained and various branching ratios are predicted.
