Abstract
Using of annihilation data taken at with the detector, precision measurements of the electromagnetic form factors of the charged pion, charged kaon, and proton have been made for timelike momentum transfer of by the reaction . The measurements are the first ever with identified pions and kaons of , with the results and . The result for the proton, assuming , is , which is in agreement with earlier results.
