Abstract:
We show that the data on and interactions can be derived from the and forward scattering amplitudes using vector meson dominance and the additive quark model. The nucleon-nucleon data are parameterized using a model where high energy cross sections rise with energy as a consequence of the increasing numbers of soft partons populating the colliding particles. We present detailed descriptions of the data on the total and elastic cross sections, the ratio of the real to imaginary part of the forward scattering amplitude, and on the slope of the differential cross sections for , , , , and reactions, where . We make a wide range of predictions for future HERA and LHC experiments and for measurements at LEP.Note:
