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

Pseudoscalar or vector meson production in non-leptonic decays of heavy hadrons [PDF]
The European Physical Journal C, 2018 We have addressed the study of non-leptonic weak decays of heavy hadrons ($$\Lambda _b, \Lambda _c, B$$Λb,Λc,B and D), with external and internal emission to give two final hadrons, taking into account the spin-angular momentum structure of the mesons ...

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

Comprehensive study of the radiative decays of J / ψ and ψ ( 2 S ) to pseudoscalar meson pairs, and search for glueballs [PDF]
, 2015 Using 53 pb$^{-1}$ of $e^+e^-$ annihilation data taken at $\sqrt{s}=3.686$ GeV, a comprehensive study has been made of the radiative decays of samples of 5.1 million $J/\psi$ and 24.5 million $\psi(2S)$ into pairs of pseudoscalar mesons, $\pi^+\pi ...

Meson exchange model for pseudoscalar meson-meson scattering [PDF]
Nuclear Physics A, 1990 A dynamical model for pseudoscalar-pseudoscalar meson scattering based on meson exchange, suitable for use in a variety of low- and intermediate-energy mesonic interactions, has been constructed and applied to ππ and kπ scattering with good quantitative results.

Effective masses of diquarks [PDF]
, 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.

Experimental test of the time-dependent Wigner inequalities for neutral pseudoscalar meson systems [PDF]
, 2015 Recently a new class of time-dependent Bell inequalities in Wigner form was introduced. The structure of the inequalities allows experimental studies of quantum and open quantum systems in external fields.

Pseudoscalar mesons and mixing models [PDF]
Zeitschrift f�r Physik C Particles and Fields, 1981 We take the charmonium state at 2.98 GeV to be the ηc and show that it can be included in quadratic and linear mass matrix mixing models, and also in those having radial excited states, in a way consistent with perturbative QCD. The effect on the models of the Crystal Ball measurement of BR (ι→γη′)/BR(ι→γη) is studied and the ratio is found to depend ...
