Further evidence for a large glue component in the f0(1500) meson

, 2002
We argue that the experimental decay rates of the f0(1500) meson into two pseudoscalar mesons and into two photons are incompatible with a quark-antiquark state and that the f0(1710) meson is dominantly an ssbar state.Comment: 11 ...

Pseudoscalar meson and decuplet baryon scattering lengths [PDF]

, 2010
We have systematically calculated the S-wave pseudoscalar meson and decuplet baryon scattering lengths to the third order in the small-scale expansion scheme of the heavy baryon chiral perturbation theory. We hope that future study may test the framework

About the quark currents in leptonic decaies of pseudoscalar mesons [PDF]

arXiv, 2006
With usage of obvious mechanisms of quark currents the amplitudes of leptonic decaies of pseudoscalar mesons are investigated. The estimation for a constant of leptonic decay of the D+ meson is obtained, f_D+ ~ 0.23 GeV.

Decay constants and form factors of s-wave and p-wave mesons in the covariant light-front quark model

, 2011
We reanalyze the decay constants of s-wave and p-wave mesons and D, B ->M form factors, where M represents a pseudoscalar meson, a vector meson, a scalar meson, or an axial vector meson within a covariant light-front quark model.

Decay Constant of Pseudoscalar Meson in the Heavy Mass Limit [PDF]

arXiv, 1999
The leptonic decay constant of the pseudoscalar mesons a calculated by use of the relativistic constituent quark model constructed on the point form of Poincare-covariant quantum mechanics. We discuss the role relativistic corrections for decay constants of pseudoscalar mesons with heavy quarks.

Mixing of eta-eta' Mesons in J/psi Decays into a Vector and a Pseudoscalar Meson

, 1997
The octet-singlet mixing angle $\theta_P$ in the pseudoscalar meson nonet is deduced from the rich set of accurate data on $J/\psi$ decays into a vector and a pseudoscalar meson.

Decay of vector-vector resonances into gamma and a pseudoscalar meson [PDF]

, 2010
We study the decay of dynamically generated resonances from the interaction of two vectors into a {gamma} and a pseudoscalar meson. The dynamics requires anomalous terms involving vertices with two vectors and a pseudoscalar, which renders it special. We

Radiative decays of mesons in the NJL model [PDF]

, 2001
We revisit the theoretical predictions for anomalous radiative decays of pseudoscalar and vector mesons. Our analysis is performed in the framework of the Nambu-Jona-Lasinio model, introducing adequate parameters to account for the breakdown of chiral ...

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

Advances 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.

Branching ratios of Bc Meson Decaying to Pseudoscalar and Axial-Vector Mesons

, 2009
We study Cabibbo-Kobayashi-Maskawa (CKM) favored weak decays of Bc mesons in the Isgur-Scora-Grinstein-Wise (ISGW) quark model. We present a detailed analysis of the Bc meson decaying to a pseudoscalar meson (P) and an axial-vector meson (A).
