Insights into Nucleon Resonances via Continuum Schwinger Function Methods
Peng Cheng, Langtian Liu, Ya Lu +1
The first baryon resonance was discovered in the early 1950s. The Roper resonance joined the collection ten years later. Today, many baryon resonances are known and more are being…
Symmetry-preserving calculation of pion light-front wave functions
Zhao-Qian Yao, Zhen-Ni Xu, Yu-Yang Xiao +2
Poincaré-covariant Bethe-Salpeter wave functions are used to calculate light-front wave functions (LFWFs) of the pion, , and an analogue state, . The current masses…
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 and Baryons
Yang Yu, Peng Cheng, Hui-Yu Xing +2
Treating baryons as quark + interacting-diquark bound states, a symmetry-preserving formulation of a vectorvector contact interaction (SCI) is used to deliver an extens…
Kaon and Pion Fragmentation Functions
Hui-Yu Xing, Wen-Hao Bian, Zhu-Fang Cui +1
The Drell-Levy-Yan relation is employed to obtain pion and kaon elementary fragmentation functions (EFFs) from the hadron-scale parton distribution functions (DFs) of these mesons.…
