Title: Spin correlations, QCD color transparency, and heavy-quark thresholds in proton-proton scattering

Abstract

The strikingly large spin-spin correlation A/sub N//sub N/ observed in pp elastic scattering at p/sub lab/ = 2.5 and 11.75 GeVc and the unexpected energy dependence of absorptive corrections to quasielastic proton-proton scattering in a nuclear target can be interpreted in terms of two J = L = S = 1, B = 2 resonance structures associated with the strange- and charmed-particle production thresholds, interfering with a perturbative QCD background. The results provide support for the ''color-transparency'' phenomenon predicted in perturbative QCD away from resonances or heavy-quark thresholds.
