Pomeron and odderon in high energypp and\(p\bar p\) elastic scattering

  • Published:
Zeitschrift für Physik C Particles and Fields

Abstract

High energypp and\(p\bar p\) data on elastic scattering and total cross sections are analyzed in a model including the pomeron, odderon and secondary reggeons. A dipole model is used for the pomeron and for the odderon. By construction, our (bare) pomeron ansatz produces a single dip, as observed experimentally. The model reproduces the logarithmically rising cross sections with a unit pomeron intercept, but better fits are obained when a small non-zero value of the parameter δ = αp (0) is allowed for. Predictions for the future accelerators (UNK, LHC, SSC) are given.
