(TH) and (EXP) HELICITY CONSERVATION IN DIFFRACTION SCATTERING f’

By F. J. Gilman, J. Pumplin, A. Schwimmer and L. Stodolsky

Abstract

We discuss the possibility that diffraction scattering of hadrons conserves the s-channel helicities of the particles involved. Presently available experimental data is examined and shown to support conservation of s-channel helicity, and not the hypothesis of no helicity,flip in the t-channel. Further tests are suggested and restrictions imposed on various models of diffraction scattering, in particular, t-channel exchange models, are discussed. (Submitted to Phys. Letters B) t Work supported by the U. S. Atomic Energy Commission.-2-Diffractive processes are an important if not key part of high energy hadron-hadron collisions. Yet in many ways such processes are the least understood. Diffraction phenomena seem to lie outside the picture which connects s-channel resonances and some t-channel exchanges’. Within the Regg
