Generalizing the Soffer Bound: Positivity Constraints on Parton Distributions of Spin-3/2 Particles
Dongyan Fu, Yubing Dong, S. Kumano +1
We derive the complete set of positivity bounds for the leading-twist parton distribution functions (PDFs) of a spin-3/2 hadron for the first time. This work generalizes the Soffer…

Transversity Generalized Parton Distributions of with the Diquark Spectator Model
Dongyan Fu, Yubing Dong, S. Kumano
We show quark transversity generalized parton pistributions (GPDs) of isobar by using the diquark spectator model for the first time. First, this model is tested by electric…

Exploring Baryon Resonances with Transition Generalized Parton Distributions: Status and Perspectives
Stefan Diehl, Kyungseon Joo, Kirill Semenov-Tian-Shansky +21
QCD gives rise to a rich spectrum of excited baryon states. Understanding their internal structure is important for many areas of nuclear physics, such as nuclear forces, dense mat…
