Measurement of electromagnetic time-like form factors of protons in BESIII — •Cristina Morales¹, Frank E. Maas¹, Paul Larin^1,2, and Dexu Lin¹ — ¹Helmholtz-Institut Mainz, SB1, Johann-Joachim-Becher-Weg 36, 55128 Mainz — ²Institut für Kernphysik, Universität Mainz, Germany

The electromagnetic form factors of protons in the time-like region are re-viewed. We present the current status of the field and emphasize the relevant role of initial state radiation processes studied in high luminosity storage rings, such as the tau-charm factory BEPCII, i.e. BES-III experiment. We also present expectations from BES-III energy-scan measurements around the proton production threshold and above.
