We evaluate axial vector transition form factors in holographic QCD models that have been shown to reproduce well recent experimental and theoretical results for the pion transition …

The recent measured γ* γ→ π 0 transition form factor in the spacelike region by the Belle Collaboration together with the previously published results by CLEO, CELLO, and BABAR …
We investigate the dependence of the chiral condensate ⟨̄qq⟩ on the temperature and quark density using the soft-wall holographic model of QCD, adopting geometries with black …
We compute the two-photon transition form factors of the light pseudoscalar π 0, η and η′ mesons in a soft-wall holographic model of QCD with a solution of the U (1) A problem. We …

We investigate the (π 0, η, η′)→ γ* γ transitions both for the spacelike region and the timelike region using the light-front quark model (LFQM). In particular, we present the new …
We explore some possibilities for obtaining useful metrics and dilatons for anti–de Sitter (AdS)/QCD models. As a guideline, we consider dilatons and/or metrics that on the one …

We compute the axial-vector and tensor meson two-photon transition form factors in the soft- wall holograhic model of QCD. They are used to evaluate the axial-vector and tensor meson …

A bstract We derive all the\(\mathcal {O}\left ({{p^ 6}}\right)\) Chiral Perturbation Theory low- energy constants from a class of gravity dual models of QCD described by the Yang-Mills …
We compute the light axial-vector and tensor meson two-photon transition form factors in the soft-wall holographic model of quantum chromodynamics (QCD) in the flavor-symmetric …
