Energy Dependence of Helicity-Flip Amplitudes in the Small-Angle Elastic pp-SCATTERING
Abstract
We discuss the role of the double helicity-flip amplitudes and derive new unitary bounds for these amplitudes in elastic pp-scattering at small values of t. We show that the usual assumption on the smallness of such amplitudes can be justified only in the region of small t values which is shrinking with energy.
