Research Interests

Professor Zheng conducts research at the Thomas Jefferson National Accelerator Facility (JLab). Her research interest includes study of the nucleon structure, especially the spin structure of the neutron using the polarized 3He target. The nucleon structure is determined by how quarks and gluons interact with each other, thus such information could reveal some fundamental properties of the strong interaction and QCD. Another major aspect of Prof. Zheng's research is parity violation (PV) in electron deep inelastic scattering (DIS). By measuring the PVDIS asymmetry off a hydrogen and a deuterium target, one could test the Standard Model of electro-weak interaction at an energy much lower than the Z-pole and to study many interesting hadronic effects such as charge symmetry violation and the asymmetry in the sea quark distribution inside the nucleon.
