Dissociation cross sections ofψ(3770),ψ(4040),ψ(4160),andψ(4415)mesons with nucleons
《Communications in Theoretical Physics》2024年第4期93-112,共20页Ruo-Qing Ding Xiao-Ming Xu H J Weber 
supported by the project STRONG-2020 of the European Center for Theoretical Studies in Nuclear Physics and Related Areas.
We study the dissociation of ψ(3770), ψ(4040), ψ(4160), and ψ(4415) mesons in collision with nucleons, which takes place in high-energy proton-nucleus collisions. The quark interchange between a nucleon and a ■ m...

On Possible S-Wave Bound States for an N-↑N System Within a Constituent Quark Model被引量:3
《Communications in Theoretical Physics》2005年第2期275-282,共8页CHANGChao-Hsi PANGHou-Rong

Electric and Magnetic Form Factors of Proton in Relativistic Constituent QuarkModel
《Communications in Theoretical Physics》2004年第3期425-428,共4页WANGHong-Min ZHANGBen-Ai 
The project supported by the Science Foundation of Chinese Academy of Engineering Physics under Contract No.42103 and for Research Doctor Subsidizes (2001)
Based on relativistic constituent quark (RCQ) model, the electric and magnetic form factors are analyzed. The ratio of the two form factors for the proton , which is an image of its charge and magnetization distributi...

Nonperturbative Aspects of Axial Vector Vertex
《Communications in Theoretical Physics》2002年第4期461-464,共4页ZONGHong-Shi CHANGChao-Hsi

Nuclear Matter in a Chiral SU(3) Quark Mean-Field Model
《Communications in Theoretical Physics》2001年第7期71-78,共8页WANG Ping ZHANG Zong-Ye YU You-Wen 
A quark meson coupling model based on SU(3)L × SU(3)R symmetry and scale invariance is proposed.The quarks and mesons get masses through symmetry broken. We apply this SU(3) chiral constituent quark model to investig...
