High-Energy Proton-Proton Scattering and Nucleon Structure: The Scalar Interaction inO(4,2)

A formula is derived from the simple scalar interaction in the relativistic $O(4,2)\mathrm{}$ model of the baryons that accounts for the high-energy proton-proton scattering at fixed angle over a cross-section range of eight decades, with a single over-all constant as the parameter. The theory also explains why there is an apparent relation between the nucleon-nucleon scattering and the electromagnetic form factors. Further implications and developments of the theory are discussed.
