Revisiting Quark Confinement in the Proton through the Force on Quarks
Ji-Xin Yu, Ao-Sheng Xiong, Ji Xu +2
Quark confinement, the fact that colored quarks are permanently bound inside color-neutral hadrons and have never been observed as isolated particles, remains one of the central is…

Exploring the neutron momentum distribution in nuclei through at an electron-positron collider
Zi-Wei Yan, Shu-man Hu, Wei Wang +3
The neutron momentum distribution is essential both for reliably extracting fundamental free neutron observables from nuclear measurements and for probing the tensor force via the…

An analysis of nuclear parton distribution function based on relative entropy
Shu-Man Hu, Ao-Sheng Xiong, Ji Xu +2
In this work, we propose a method to quantify the difference between nuclear parton distribution functions in different nuclei and parton distribution functions in free nucleons us…
