Oscillatory Scaling Violations and the Quantum Chromodynamic Coulomb Phase

The exchange of gluons in the initial or final state of hard processes is shown to build a Q/sup 2/-dependent phase shift which may be observed as an oscillatory scaling violation in infrared dominated processes. The non-Abelian structure of the phase can affect cross sections for experiments as diverse as pp elastic scattering at fixed angle and dilepton production in hadronic collisions, resulting in oscillatory components. The oscillations may already have been detected.
