Correlated Scattering and Cluster Planes

We suggest a new correlation in diffractive production of 2 “clusters” A + B → AB with large intrinsic angular momenta for each A and B cluster. These correlations are expected in the context of the “color dipole picture” for high energy collision and reflect the approximate conservation of dipole direction during the collision. This conservation is in particular manifest when the two dipoles, ~ dA, ~ dB and the impact vector ̃ b are all parallel. The predicted positive triple correlation is between the momentum transfer ̃ ∆ and the planes of the A and B clusters. QCD is well-tested in the short distance perturbative regime, yet it cannot predict the bulk of hadronic scattering data without additional “models” and approximations. ∗E-mail: [email protected]
