About the creation of proton-anti-proton pair at electron-positron collider in the energy range of the mass
The process of electron--positron annihilation into proton--antiproton pair
is considered within the vicinity of resonance. The interference
between the pure electromagnetic intermediate state and the state
is evaluated. It is shown that this interference is destructive and the
relative phase between these two contributions is large ().Comment: 16 pages, 6 figures. The authors included the long-range
contributions (D-meson loop) in their calculations. The conclusion of the
papers did not chang
