Insights into Meson and Baryon Structure using Continuum Schwinger Function Methods
Daniele Binosi, Craig D. Roberts, Zhao-Qian Yao
The bulk of visible mass is supposed to emerge from nonperturbative dynamics within quantum chromodynamics (QCD). Following years of development and refinement, continuum and latti…
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…
Light-Front Transverse Nucleon Charge and Magnetisation Densities
Z. -N. Xu, Z. -Q. Yao, P. Cheng +3
Nucleon elastic electromagnetic form factors obtained using both the three-body and quark + fully-interacting-diquark pictures of nucleon structure are employed to calculate an arr…
Quark + Diquark Description of Nucleon Elastic Electromagnetic Form Factors
Peng Cheng, Zhao Qian Yao, Daniele Binosi +2
Working with a Poincaré-covariant quark + diquark, , Faddeev equation approach to nucleon structure, a refined symmetry preserving current for electron + nucleon elastic sca…
Distribution Functions of a Radially Excited Pion
Z. -N. Xu, Z. -Q. Yao, D. Binosi +3
A nonperturbatively-improved, symmetry-preserving approximation to the quantum field equations relevant in calculations of meson masses and interactions is used to deliver predicti…
Nucleon Gravitational Form Factors
Z. -Q. Yao, Y. -Z. Xu, D. Binosi +6
A symmetry-preserving analysis of strong interaction quantum field equations is used to complete a unified treatment of pion, kaon, nucleon electromagnetic and gravitational form f…
Developing predictions for pion fragmentation functions
H. -Y. Xing, Z. -Q. Yao, B. -L. Li +3
Exploiting crossing symmetry, the hadron scale pion valence quark distribution function is used to predict the kindred elementary valence quark fragmentation function (FF). This fu…
