Lepton Flavour Universality in Semileptonic Transitions
Yu-Chen Hu, Cong-Cong Ye, Craig D. Roberts +1
Using continuum Schwinger function methods, we deliver parameter-free pointwise predictions for the complete set of twelve Standard Model (SM) ,…
Neutral Pseudoscalar Mesons, Hadron Light-by-Light Scattering, and the Muon Anomalous Magnetic Moment
Cong-Cong Ye, Yu-Chen Hu, Minghui Ding +1
Continuum Schwinger function methods\linebreak (CSM) are used to provide estimates of pseudoscalar meson pole contributions - , , , , - to…
Orbital angular momentum in the pion and kaon: rest-frame and light-front
Y. -Y. Xiao, Z. -N. Xu, Z. -Q. Yao +2
Orbital angular momentum (OAM) is not a Poincaré invariant quantity; so, its value is observer dependent. Notwithstanding that, in quantum chromodynamics, a Poincaré-invariant theo…
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…
Exclusive photoproduction of light and heavy vector mesons: thresholds to very high energies
Lin Tang, Hui-Yu Xing, Minghui Ding +1
A reaction model for , , which exposes the quark-antiquark content of the photon in making the transition , wh…
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…
