Correlated Scattering and Cluster Planes

Abstract

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.
