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…
Symmetry Constraints on Pion Valence Structure
Xiaobin Wang, Lei Chang, Minghui Ding +2
The profile of the pion valence quark distribution function (DF) remains controversial. Working from the concepts of QCD effective charges and generalised parton distributions, we…
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…
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…
Pion, Kaon and nucleon gravitational form factors
Zhao-Qian Yao, Yin-Zhen Xu, Daniele Binosi +5
A unified set of predictions for pion, kaon and nucleon gravitational form factors is obtained using a symmetry-preserving truncation of each relevant quantum field equation. A cru…
