Extrapolation of diffraction peaks to SSC energies

The authors observed that the Cheng-Walker-Wu model of 1973 which is based on an eikonal-type model, predicts a shoulder in the pp and anti pp differential cross sections at the SPS energy. This feature is now confirmed by the anti pp data at √ s = 540 GeV. Assuming that the eikonal model is indeed approximately valid in the sub-TeV and TeV region, the authors propose a simple modification to the CWW model. The modified model can now quantitatively account for the energy dependence of the diffractive peak at the ISR and SPS energies. Extrapolations of the diffractive peak up to 40 TeV are presented
