Mass Spectrum of Noncharmed and Charmed Meson States in Extended Linear-Sigma Model
ParticlesThe mass spectrum of different meson particles is generated using an effective Lagrangian of the extended linear-sigma model (eLSM) for scalar and pseudoscalar meson fields and quark flavors, up, down, strange, and charm.

Meson electromagnetic form factors
EPJ Web of Conferences, 2012 The electromagnetic structure of the pseudoscalar meson nonet is completely described by the sophisticated Unitary&Analytic model, respecting all known theoretical properties of the corresponding form factors.

Electromagnetic Transition Form Factors of Mesons
, 2011 Using a counting scheme which treats pseudoscalar and vector mesons on equal footing, the decays of the narrow light vector mesons omega and phi into a dilepton and a pseudoscalar pi-meson or eta-meson, respectively, are calculated. Thereby, all required

On the mass relation of a meson nonet [PDF]
, 2002 It is pointed out that the omission of the effects of the transition between quarkonia or the assumption that the transition between quarkonia is flavor-independent would result in the inconsistent results for the pseudoscalar meson nonet.

Meson properties at finite temperature in a three flavor nonlocal chiral quark model with Polyakov loop [PDF]
, 2010 We study the finite temperature behavior of light scalar and pseudoscalar meson properties in the context of a three-flavor nonlocal chiral quark model. The model includes mixing with active strangeness degrees of freedom, and takes care of the effect of

Study of Semileptonic B⟶DPℓ+νℓ Decays Based on the SU(3) Flavor Symmetry
Advances in High Energy Physics, Volume 2025, Issue 1, 2025.Decays B⟶DPℓ+νℓ(ℓ = e, μ, τ) with the nonresonance, the charmed vector resonances, the charmed scalar resonances, and the charmed tensor resonances are explored by using the SU(3) flavor symmetry approach. Firstly, the decay amplitudes of different modes are related by the SU(3) flavor symmetry.

Gamma-gamma physics and meson transition form factors [PDF]
EPJ Web of Conferences, 2020 I summarize recent experimental results for two photon production of mesons. These processes include the neutral pion, η and η′ transition form factors and two photon production of pseudoscalar meson pairs.

Tensor Condensate Accompanied by Chiral Transition in a Strong Magnetic Field
Advances in High Energy Physics, Volume 2025, Issue 1, 2025.We investigate tensor condensates and chiral condensates in the (2 + 1)‐flavor Nambu–Jona–Lasinio model at finite temperature and density in the presence of a strong magnetic field. The emergence of the tensor condensate is attributed to the four‐fermion interaction.

Physics Letters B, 2022 We carry out the first lattice QCD derivation of the mixing energy and the mixing angle of the pseudoscalar charmonium and glueball on two gauge ensembles with Nf=2 degenerate dynamical charm quarks. The mixing energy is determined to be 49(6) MeV on the
