Electromagnetic form factors of singly charmed baryons and in a covariant quark-diquark model
Ye Cao, Cheng Chen, Dongyan Fu +1
We present a systematic study of the spacelike electromagnetic form factors of the ground-state singly charmed baryons, () and , within a co…
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…
A D_5 Model of Quarks with Explicit CP Violation
Dong-Ping Fu, Michihisa Takeuchi
We investigate the quark sector of a four-Higgs-doublet model with an exact D_5 symmetry. In the framework of explicit CP violation, we considered the most general real vacuum, der…
Form factors of (1232) and the electromagnetic transition
Jiaqi Wang, Dongyan Fu, Yubing Dong
In this work, the electromagnetic and gravitational form factors of isobars, as well as the electromagnetic transition form factors are studied systematically and conti…
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…
A systematical study of the nucleon form factors with the pion cloud effect
Jiaqi Wang, Dongyan Fu, Yubing Dong
The electromagnetic and gravitational form factors of the nucleon are studied simultaneously using a covariant quark-diquark approach, and the pion cloud effect on the form factors…
