On decays of light unflavoured pseudoscalar mesons [PDF]
arXiv, 2011 The ongoing and planned experimental activities with direct reference to light unflavoured pseudoscalar mesons motivate a new theoretical study regarding their properties. An overview including details on new precise calculations is presented.

Pseudoscalars and the η′ in the holographic soft-wall model [PDF]
EPJ Web of Conferences, 2022 Pseudoscalar mesons and glueballs are studied in a model based on the AdS/QCD correspondence. Glueball masses are obtained in the pure-gauge case, while the mixing between pseudoscalar glueballs and singlet pseudoscalar mesons produces the expected mass ...

Potential higher radial excitations in the light pseudoscalar meson family [PDF]
Physical Review D, 2020 Inspired by the event accumulation around 2.6 GeV in the $\eta^\prime\pi^+\pi^-$ invariant mass spectrum of $J/\psi\to \gamma \eta^\prime\pi^+\pi^-$, which was reported by the BESIII Collaboration, we carry out the study of the mass spectrum and decay ...

ON THE COMPLEXION OF PSEUDOSCALAR MESONS [PDF]
International Journal of Modern Physics A, 2005 A strongly momentum-dependent dressed-quark mass function is basic to QCD. It is central to the appearance of a constituent-quark mass-scale and an existential prerequisite for Goldstone modes. Dyson-Schwinger equation (DSEs) studies have long emphasised this importance, and have proved that QCD's Goldstone modes are the only pseudoscalar mesons to ...

Mass dependence of pseudoscalar meson elastic form factors [PDF]
Physical Review D, 2018 A continuum approach to quark-antiquark bound-states is used to determine the electromagnetic form factors of pion-like mesons with masses $m_{0^-}/{\rm GeV}=0.14$, $0.47$, $0.69$, $0.83$ on a spacelike domain that extends to $Q^2 \lesssim 10\,$GeV$^2 ...

Finite size effect on pseudoscalar meson sector in 2+1 flavor QCD at the physical point [PDF]
Physical Review D, 2018 We investigate the finite size effect on pseudoscalar meson masses and decay constants using a subset of the "PACS10" configurations which are generated keeping the space-time volumes over (10 fm$)^4$ in 2+1 flavor QCD at the physical point.
