Helicity Dependent Distribution Functions of the Proton and and Baryons
Yang Yu, Peng Cheng, Hui-Yu Xing +2
Using continuum Schwinger function methods, a coherent set of predictions for proton, and distribution functions (DFs) has been made available -- both helicity dependen…
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…
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…
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 sc…
Likelihood of a zero in the proton elastic electric form factor
Peng Cheng, Zhao-Qian Yao, Daniele Binosi +1
Working with the available data on the ratio of proton electric and magnetic form factors, , and independent of any model or theory of strong inte…
