The observing scale of the universe is estimated to be about 100 billion light-years (1027 meters). While the scale of the nucleon, the primary building block to the visible universe, is only 10-15 meters. Over half century, our understanding on the nucleon internal structure has obtained great success. However, many fundamental questions still remain, such as the origin of the nucleon spin and mass, etc. This is usually experimentally pursued via point-like lepton scattering off nucleons, targeting at the fundamental questions of understanding the constitute interactions and the emergence of nucleon from the dynamics of quarks and gluons.
The Nucleon Structure Group of Quark Matter Research Center(QMRC) focuses on studies in the field of hadron physics, including both the nucleon structure and the hadron spectroscopy. The group participates in international cooperation and promotes the Electron ion collider in China (EicC) project, which was proposed by IMP.
The conceptual design of Electron-ion collider in China
1. Theoretical and experimental study on nucleon structure— 1-D spin structure, 3-D nucleon internal structure (TMDs, GPDs),nuclear internal structure, proton mass decomposition and exotic states. Participate in experiments in Jefferson Lab and high energy EIC in Brookhaven National Laboratory.
2. Theoretical and experimental study on hadron spectroscopy, light hadron spectroscopy and exotic states. Participate in BESIII, PANDA, and STCF (Super Tau-Charm Facility in China).
3. Promote the EicC project and advanced detector technologies.
