Pion transverse charge density and the edge of hadrons.

The article discusses the study conducted which uses the pion form factor for space-like kinematics to extract the proton transverse charge density and its uncertainty. Topics discussed include propagation patterns of mesons, existence of a kaon-nucleon in-medium potential, and use of Jefferson National Accelerator Facility (JLab) 12 Gigaelectro volt and the Electron-Ion Collider (EIC) for the study.
