Description
Summary:Nucleon-antinucleon optical potential, which explains the experimental data for the processes e super(+)e super(-) arrow right pp and e super(+)e super(?) arrow right pions near the threshold of pp pair production, is suggested. To obtain this potential, we have used the available experimental data for pp scattering, pp pair production in e super(+)e super(?) annihilation, and the ratio of electromagnetic form factors of a proton in the timelike region. It turns out that final-state interaction via the optical potential allows one to reproduce the available experimental data with good accuracy. Our results for the cross sections of the e super(+)e super(?) arrow right 6[pi] process near the threshold of pp pair production are in agreement with the recent experiments.
