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

Pseudoscalar meson form factors and decays [PDF]
, 2011 In this communication we discuss few topics related with modern experimental data on the physics of light pseudoscalar mesons. It includes the contribution of the pseudoscalar mesons to the muon anomalous magnetic moment (AMM), $g-2$, the rare decays of light pseudoscalar mesons to lepton pair, the transition form factors of pseudoscalar mesons at ...

Electromagnetic structure and weak decay of pseudoscalar mesons in a light-front QCD-inspired model
, 2005 We study the scaling of the $^3S_1-^1S_0$ meson mass splitting and the pseudoscalar weak decay constants with the mass of the meson, as seen in the available experimental data.

Leading isospin-breaking effects on the lattice [PDF]
, 2017 Isospin is an almost exact symmetry of strong interactions and the corrections to the isosymmetric limit are, in general, at the percent level. For several hadronic quantities, such as pseudoscalar meson masses or the kaon leptonic and semileptonic decay

Determining pseudoscalar meson photoproduction amplitudes from complete experiments [PDF]
, 2010 A new generation of complete experiments is focused on a high precision extraction of pseudoscalar meson photoproduction amplitudes. Here, we review the development of the most general analytic form of the cross section, dependent upon the three ...

Contributions of loops with dynamical vector mesons to masses and decay constants of pseudoscalar mesons and their quark mass dependence [PDF]
arXiv, 2016 The contributions of one-loop diagrams with dynamical vector mesons to masses and decay constants of pseudoscalar mesons are determined. Hereby, a relativistic Lagrangian for both the pseudoscalar-meson octet and the vector-meson nonet is used. The vector mesons are given in the antisymmetric tensor representation.

Composition of the pseudoscalar η and η′ mesons [PDF]
Journal of High Energy Physics, 2007 The composition of the eta and eta' mesons has long been a source of discussion and is of current interest with new experimental results appearing. We investigate what can be learnt from a number of different processes: V to P gamma and P to V gamma (V and P are light vector and pseudoscalar mesons respectively), P to gamma gamma, J/psi,psi' to P gamma,

European 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 ...
