Abstract

The process e+e-→pp̅ γ is studied using 469  fb-1 of integrated luminosity collected with the BABAR detector at the SLAC National Accelerator Laboratory, at an e+e- center-of-mass energy of 10.6 GeV. From the analysis of the pp̅ invariant mass spectrum, the energy dependence of the cross section for e+e-→pp̅ is measured from threshold to 4.5 GeV. The energy dependence of the ratio of electric and magnetic form factors, |GE/GM|, and the asymmetry in the proton angular distribution are measured for pp̅ masses below 3 GeV. The branching fractions for the decays J/ψ→pp̅ and ψ(2S)→pp̅ are also determined.
