Abstract

Using 20.7 pb(-1) of e(+)e(-) annihilation data taken at root s = 3.671 GeV with the CLEO-c detector, precision measurements of the electromagnetic form factors of the charged pion, charged kaon, and proton have been made for timelike momentum transfer of vertical bar Q(2 vertical bar)=13.48 GeV2 by the reaction e(+)e(-)-> h(+)h(-). The measurements are the first ever with identified pions and kaons of vertical bar Q (2)vertical bar > 4 GeV2, with the results F-pi(13.48 GeV2) = 0.075 +/- 0.008(stat)+/- 0.005(syst) and F-K(13.48 GeV2) = 0.063 +/- 0.004(stat)+/- 0.001(syst). The result for the proton, assuming G(E)(p)=G(M)(p), is G(M)(p)(13.48 GeV2) = 0.014 +/- 0.002(stat)+/- 0.001(syst), which is in agreement with earlier results.
