Neutral pion to two-photons transition form factor revisited
M. Atif Sultan, Jiayin Kang, Adnan Bashir +1
Based upon a combined formalism of Schwinger-Dyson and Bethe-Salpeter equations in quantum chromodynamics (QCD), we propose a QCD kindred algebraic model for the dressed quark prop…

Contact interaction treatment of for light-quark mesons
Yehan Xu, M. Atif Sultan, Khépani Raya +1
The and decays are evaluated within a Dyson-Schwinger and Bethe-Salpeter equations framework (here $\mathcal{V}=\{ρ^{\pm},K^{\star…

Gravitational form factors of pseudoscalar mesons in a contact interaction
M. Atif Sultan, Zanbin Xing, Khépani Raya +2
Given the unique role played by the gravitational form factors (GFFs) in unraveling the internal mechanics of hadrons, we examine the GFFs of ground state pseudoscalar mesons ,…
