Nucleons are bound within the nucleus via the strong interaction, yet a bridge between Quantum Chromodynamics (QCD) and effective mean-field theories remains elusive. Short-Range Correlations (SRC)—transient, high-density clusters formed by overlapping nucleons—offer a unique experimental window into this fundamental gap. Driven by the interplay of strong tensor forces and short-range repulsive cores, SRCs provide critical insights into amplified multi-nucleon forces, the role of quark-gluon degrees of freedom in nuclear ground states and the internal structure of neutron stars. Furthermore, SRCs are intrinsically linked to the EMC effect, which signifies the modification of quark distributions in bound nucleons. Understanding this connection is essential for reconciling nuclear and nucleon structures and for modeling high-density matter, such as that found in neutron stars. In this talk, I will discuss experimental approaches to probing SRCs, focusing on recent results from Thomas Jefferson Lab (JLab), potential research opportunities at the new CEE detector at CSR (Institute of Modern Physics), as well as future experimental programs at the HIAF facility in China.
About the speaker: Prof. Zhihong Ye received his B.S. degree from Lanzhou University and his Ph.D. in experimental medium-energy physics from the University of Virginia. He then worked as a postdoc at Duke University and Argonne National Lab and later as a senior research associate at Argonne National Lab. He also briefly worked at Canon Inc. Medical Research Institute developing the new generation photon-counting CT. He joined Tsinghua University in 2021 in the Department of Physics and continues to work on experiments at JLab. He is also actively involved in the development of future experimental projects in China. His research topics include SRC and EMC effects, proton form-factors and charged-radius, and 3D quark structures in nucleons and nuclei.
