Meson electromagnetic form factors [PDF]
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.

Heavy + light pseudoscalar meson semileptonic transitions [PDF]
European Physical Journal C: Particles and Fields, 2021 A symmetry-preserving regularisation of a vector $$\times $$ × vector contact interaction (SCI) is used to deliver a unified treatment of semileptonic transitions involving $$\pi $$ π , K, $$D_{(s)}$$ D ( s ) , $$B_{(s,c)}$$ B ( s , c ) initial states ...

The Pseudoscalar Meson and Heavy Vector Meson Scattering Lengths [PDF]
Physical 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

Quark structure of pseudoscalar mesons [PDF]
International Journal of Modern Physics A, 1999 I review to which extent the properties of pseudoscalar mesons can be understood in terms of the underlying quark (and eventually gluon) structure. Special emphasis is put on the progress in our understanding of eta-eta' mixing.

The role of meson exchanges in light-by-light scattering
Physics Letters B, 2017 We discuss the role of meson exchange mechanisms in γγ→γγ scattering. Several pseudoscalar (π0, η, η′(958), ηc(1S), ηc(2S)), scalar (f0(500), f0(980), a0(980), f0(1370), χc0(1P)) and tensor (f2(1270), a2(1320), f2′(1525), f2(1565), a2(1700)) mesons are ...

Pseudoscalar Mesons and Emergent Mass [PDF]
Few-Body SystemsAbstractDespite its role in the continuing evolution of the Universe, only a small fraction of the mass of visible material can be attributed to the Higgs boson alone. The overwhelmingly dominant share may/should arise from the strong interactions that act in the heart of nuclear matter; namely, those described by quantum chromodynamics.

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 ...
