Phenomenological study on the image reactions

We extend our recent phenomenological study of image reactions to the image reactions for anti-proton beam momenta up to 3.0 GeV within an effective Lagrangian approach. The contribution of image with its Nσ decay mode is found to be dominant at the energies close to threshold for image and image channels. At higher energies or for image and image channels where image mode cannot contribute, large contributions from double-Δ, image, image and image are found. In the near-threshold region, sizeable contributions from image, image, image and nucleon pole are also indicated. Although these results are similar to those for image reactions, the antinucleon–nucleon collisions are shown to be complementary to the nucleon–nucleon collisions and may even have advantages in some aspects. The PANDA/FAIR experiment is suggested to be an excellent place for studying the properties of relevant image and image resonances.
