  Precise Electromagnetic Structure of Neutron Measured at BESIII The BESIII collaboration presented measurements of the neutron’s electromagnetic (EM) structure in the time-like region with unprecedented precision. The new BESIII results clarify the photon-nucleon interaction puzzle that has persisted for over 20 years, and a surprising periodic structure is observed on the nucleon effective form factors. The manuscript is featured on the cover of the Nature Physics issue of Nov.8th, 2021.
