Abstract: (APS)
The strikingly large spin-spin correlation ANN observed in pp elastic scattering at plab=2.5 and 11.75 GeV/c 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.
