W-meson production in proton-antiproton annihilations

Abstract

The cross-sections for W-meson production with a single pion or kaon in proton-antiproton annihilations have been calculated using a model in which single-meson intermediate states dominate. Considerations of unitary symmetry and ω-π mixing, previously discussed in connection with annihilation into strongly interacting mesons only as well as W-meson decays, have been combined in the calculations. We find that the predicted cross-sections are large enough to suggest that W mesons may be observable in annihilation reactions at high energies.
