Radiative decays of vector and pseudoscalar nonets

open access: yesEPJ Web of Conferences, 2012
Using a counting scheme which treats the light pseudoscalar and the light vector-meson nonet on equal footing, the decays of the narrow light vector mesons into a pseudoscalar meson and a dilepton and of the η′ meson into an ɷ meson and a dielectron are ...

Pseudoscalar meson and heavy vector meson scattering lengths [PDF]

open access: yesPhysical Review D, 2011
We have systematically studied the S-wave pseudoscalar meson and heavy vector meson scattering lengths to the third order with the chiral perturbation theory, which will be helpful to reveal their strong interaction. For comparison, we have presented the numerical results of the scattering lengths (1) in the framework of the heavy meson chiral ...

The Ds0(2590)+ as the dressed cs¯(21S0) meson in a coupled-channels calculation

open access: yesPhysics Letters B, 2022
The recent discovery of the Ds0(2590)+ meson by the LHCb Collaboration has stimulated the analysis of meson-meson channels effects in the two-body quark-antiquark meson spectrum.

Hidden gauge formalism for the radiative decays of axial-vector mesons [PDF]

open access: yes, 2008
The radiative decay of the axial-vector resonances into a pseudoscalar meson and a photon is studied using the vector meson Lagrangian obtained from the hidden gauge symmetry (HGS) formalism.

Phase shifts of the light pseudoscalar meson and heavy meson scattering in heavy meson chiral perturbation theory

open access: yesEuropean Physical Journal C: Particles and Fields, 2023
We calculate the complete T matrices of the elastic light pseudoscalar meson and heavy meson scattering to the third order in heavy meson chiral perturbation theory. We determine the low-energy constants by fitting the phase shifts and scattering lengths

Soft two-meson-exchange nucleon-nucleon potentials. I. Planar and crossed-box diagrams [PDF]

open access: yes, 1996
Pion-meson-exchange nucleon-nucleon potentials are derived for two nucleons in the intermediate states. The mesons we include are (i) pseudoscalar mesons: $\pi, \eta, \eta'$; (ii) vector mesons: $\rho, \omega, \phi$; (iii) scalar mesons: $a_{0}(980 ...

Decay of the pseudoscalar glueball into vector, axial-vector, scalar and pseudoscalar mesons

open access: yesEuropean Physical Journal C: Particles and Fields, 2023
We resume the investigation of the ground-state pseudoscalar glueball, $$J^{PC}=0^{-+}$$ J PC = 0 - + , by computing its two- and three-body decays into vector and axial-vector quark-antiquark meson fields additional to scalar and pseudoscalar mesons ...

Effective masses of diquarks [PDF]

open access: yes, 2002
We study meson and diquark bound states using the rainbow-ladder truncation of QCD's Dyson-Schwinger equations. The infrared strength of the rainbow-ladder kernel is described by two parameters.
