Abstract

The possibility of measuring the proton electromagnetic form factors in the time-like region at FAIR with the P¯¯¯¯ANDA detector is discussed. Detailed simulations on signal efficiency for the annihilation of p¯ + p into a lepton pair as well as for the most important background channels have been performed. It is shown that precise measurements of the differential cross-section of the reaction p¯ + p→e- + e+ can be obtained in a wide kinematical range. The determination of the ratio R of the moduli of the electric and magnetic proton form factors will be possible up to a value of momentum transfer squared of q2 ≃ 14 (GeV/c)^2 with absolute precision from 0.01 to 0.5 (for R ∼ 1 . The total p¯ + p→e- + e+ cross-section will be measured up to q2 ≃ 28 (GeV/c)^2. The results obtained from simulated events are compared to the existing data. Sensitivity to the two-photon exchange mechanism is also investigated.
