Meson–baryon coupling constants of the SU(3) baryons with flavor SU(3) symmetry breaking

open access: yesPhysics Letters B, 2018
We investigate the strong coupling constants for the baryon octet–octet, decuplet–octet, and decuplet–decuplet vertices with pseudoscalar mesons within a general framework of the chiral quark-soliton model, taking into account the effects of flavor SU(3)

Annihilation Diagrams in Two-Body Nonleptonic Decays of Charmed Mesons

open access: yes, 1993
In the pole-dominance model for the two-body nonleptonic decays of charmed mesons $D \rightarrow PV$ and $D \rightarrow VV$, it is shown that the contributions of the intermediate pseudoscalar and the axial-vector meson poles cancel each other in the ...

DCC dynamics with the SU(3) linear sigma model [PDF]

open access: yes, 1998
The SU(3) extension of the linear sigma model is employed to elucidate the effect of including strangeness on the formation of disoriented chiral condensates.

Strong decays of vector mesons to pseudoscalar mesons in the relativistic quark model

open access: yesPhysics Letters B, 2015
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.

Covariant QCD Modeling of Light Meson Physics [PDF]

open access: yes, 2003
We summarize recent progress in soft QCD modeling based on the set of Dyson--Schwinger equations truncated to ladder-rainbow level. This covariant approach to hadron physics accommodates quark confinement and implements the QCD one-loop renormalization ...

Direct CP Violation from Isospin Symmetry Breaking Effects for the Decay Process B-s→P(V)π0 in PQCD

open access: yesAdvances in High Energy Physics, 2019
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.

An Analysis of the Decay $B \rightarrow D^* X \ell \bar\nu_\ell$ with Predictions from Heavy Quark and Chiral Symmetry

open access: yes, 1992
This paper considers the implications of the heavy quark and chiral symmetries for the semi-leptonic decay $B \rightarrow D^* X \ell \bar \nu_\ell$. The general kinematic analysis for decays of the form {\sl pseudoscalar meson $\rightarrow$ vector meson $

Study of the interactions of the axion with mesons and photons using a chiral effective Lagrangian model

open access: yesEuropean Physical Journal C: Particles and Fields, 2020
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 ...

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

open access: yesEuropean 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.

Mapping Spatial Distributions within Pseudoscalar Mesons

open access: yesChinese Physics Letters
Abstract Several aspects of the internal structure of pseudoscalar mesons, accessible through generalized parton distributions in their zero-skewness limit, are examined. These include electromagnetic and gravitational form factors related to charge and mass densities; and distributions in the impact parameter space.
