Empirical Determination of the Kaon Distribution Amplitude
Lei Chang, Yu-Bin Liu, Khépani Raya +1
We propose a data-driven approach to extract the Kaon leading-twist distribution amplitude (DA) from empirical information on the ratio of the neutral-to-charged kaon electromagnet…
Bottomonium meson spectrum with quenched and unquenched quark models
M. Atif Sultan, Wei Hao, E. S. Swanson +1
An open question in hadronic phenomenology concerns the ``unquenching" effects of higher Fock space components on the leading Fock space description of hadrons. We address this by…
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 ,…
QCD anomalies in electromagnetic processes: A solution to the puzzle
Zanbin Xing, Hao Dang, M. Atif Sultan +2
In this work, the form factor is calculated within the Dyson-Schwinger equations framework using a contact interaction model within the so-called modified rainbow ladder t…
