Radiative charmonium decays in a contact-interaction model with dynamical quark anomalous magnetic moment

Yehan Xu, Zanbin Xing, Khépani Raya +1

The BESIII Collaboration has recently reported two measurements of the two-photon decay width of the meson. The 2024 result is significantly larger than most theoretical and…

A Direct Algebraic Pathway to Hadronic Observables in the Contact Model

Jiayin Kang, Zanbin Xing, Lei Chang

We present a novel algebraic framework for computing hadron properties directly within the contact interaction model. Utilizing Fierz transformations, the method recasts the Bethe-…

The Dichotomous Nature of the Meson and the Nucleon D-Term

Zanbin Xing, Khépani Raya, Yu-xin Liu +1

Employing a symmetry-preserving contact-interaction formulation of the Dyson-Schwinger equations in quantum chromodynamics (QCD), we examine the identity of the meson and its i…

Electromagnetic structure of axial-vector mesons and implications for the muon

Zanbin Xing, Lei Chang, Khépani Raya

The electromagnetic structure of axial-vector mesons is investigated via elastic and two-photon transition form factors (TFFs). To this end, we employ a framework based on the Dyso…

Sketching pion and proton mass distributions

Xiaobin Wang, Zanbin Xing, Lei Chang +3

A light-front holographic model is used to illustrate an algebraic scheme for constructing a representation of a hadron's zero-skewness generalised parton distribution (GPD) from i…

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 ,…

Bridging Electromagnetic and Gravitational Form Factors: Insights from LFHQCD

Xiaobin Wang, Zanbin Xing, Minghui Ding +2

We propose an efficacious approach to derive the generalized parton distributions for the pion and proton, based upon prior knowledge of their respective parton distribution functi…

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…

The chiral anomaly and the pion transition form factor: beyond the cutoff

Hao Dang, Zanbin Xing, M. Atif Sultan +2

In the presence of a momentum cutoff, effective theories seem unable to faithfully reproduce the so called chiral anomaly in the Standard Model. A novel prospect to overcome this r…

A fresh look at the generalized parton distributions of light pseudoscalar mesons

Zanbin Xing, Minghui Ding, Khépani Raya +1

We present a symmetry-preserving scheme to derive the pion and kaon generalized parton distributions (GPDs) in Euclidean space. The key to maintaining crucial symmetries under this…
