 Time-like observables: differential cross section and angular asymmetry
 (2008)
 Time-like electromagnetic form factors can be obtained from unpolarized measurements of the differential cross section in proton antiproton annihilation in a pair of leptons, as $\overline{p}$ + p ↔ e+ + e− , with the PANDA detector at FAIR. We study the sensitivity of such measurements and focus on observables such as the angular asymmetry and the ratio of electric to magnetic form factors. We also collect useful formulas and references for future simulations and studies.
