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…

Electromagnetic form factors of with the meson cloud in the spacelike and timelike regions

Dongyan Fu, Ju-Jun Xie, Yubing Dong

We present comprehensive calculations of the electromagnetic form factors, including the charge, magnetic-dipole, electric-quadrupole and magnetic-octupole form factors, of the $Ω^…

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…

Electromagnetic and gravitational form factors of resonance in a covariant quark-diquark approach

Dongyan Fu, Bao-Dong Sun, Yubing Dong

In this work, the electromagnetic and gravitational form factors of a spin- particle, resonance, are simultaneously calculated with the help of a relativistic covariant qu…
