Strong decays of vector mesons to pseudoscalar mesons in the relativistic quark model
Strong decays of vector (S13) mesons to the pair of pseudoscalar (S01) mesons are considered in the framework of the microscopic decay mechanism and the relativistic quark model based on the quasipotential approach.

Direct CP Violation from Isospin Symmetry Breaking Effects for the Decay Process B-s→P(V)π0 in PQCD
We investigate the direct CP violation for the decay process of B-s→P(V)π0 (P,V refer to the pseudoscalar meson and vector meson, resp.) via isospin symmetry breaking effects from the π0-η-η′ mixing mechanism in PQCD factorization approach.

Weak decays of $$B_c$$ Bc into two hadrons under flavor SU(3) symmetry
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.

We investigate the most interesting decay processes involving axions, photons and the lightest pseudoscalar mesons, making use of a chiral effective Lagrangian model with $$L=3$$ L=3 light quark flavors, which also includes the flavor-singlet ...

B0 and Bs0 decays into J/ψ f0(980) and J/ψ f0(500) and the nature of the scalar resonances
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.

Based on the predictions of the relevant form factors from the covariant light-front quark model, we show the branching fractions for the $$D (D_s) \rightarrow (P,\,S,\,V,\,A)\,\ell \nu _\ell $$ D ( D s ) → ( P , S , V , A ) ℓ ν ℓ ( $$\ell =e$$ ℓ = e or $

Composition of the pseudoscalar η and η′ mesons [PDF]
The composition of the eta and eta' mesons has long been a source of discussion and is of current interest with new experimental results appearing. We investigate what can be learnt from a number of different processes: V to P gamma and P to V gamma (V and P are light vector and pseudoscalar mesons respectively), P to gamma gamma, J/psi,psi' to P gamma,
