Spin Observables for Nucleon-Nucleon Elastic Scattering at Large Momentum Transfer

  • G. P. Ramsey
Conference paper


We discuss amplitudes for elastic nucleon-nucleon scattering at high energy. The helicity-conserving amplitudes are modeled using a combination of the quark-interchange and the Landshoff mechanisms of perturbative QCD. The relative normalization of these two sets of amplitudes involves a “leading order form factor” which we determine empirically. Our theoretically motivated amplitudes provide an economical description of a large body of existing data and make nontrivial predictions for spin observables.
