Proton Timelike Form Factors Near Threshold via Antiproton-Nucleus Electromagnetic Annihilation

V. A. Karmanov, H. Fonvieille

In the reaction of the antiproton-deuteron electromagnetic annihilation pbar + d --> e+e-n the value of the invariant mass M of the (e+e-) pair can be near or below the (pbar p) ma…
