Correlated Scattering and Cluster Planes

We suggest a new correlation in diffractive production of 2 ``clusters'' $A+B\to A^\ast B^\ast$ with large intrinsic angular momenta for each $A^\ast$ and $B^\ast$ 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, $\vec d_A$, $\vec d_B$ and the impact vector $\undtilb$ are all parallel. The predicted positive triple correlation is between the momentum transfer $\undtildel$ and the planes of the $A^\ast$ and $B^\ast$ clusters.
