Abstract

The compatibility of $s$ -channel helicity conservation and $t$ -channel exchanges in diffractive-type processes is examined. It is found that compatibility exists only in the infinite-energy limit. This requires specification of ratios of residue or vertex functions for $t$ -channel helicity amplitudes. Assuming these conditions are satisfied, finite-energy corrections for $ρ^{0}$ polarized photoproduction are calculated and found to be consistent with data at 2.8 and 4.7 GeV. Predicted values of spin-density matrix elements for other diffractive processes are given for the usual $t$ -channel analysis in unpolarized experiments.
