Abstract
We present results on charm pair correlations measured in proton-emulsion interactions at s=38.7 GeV. The predictions of leading order QCD for the distributions in invariant mass, rapidity gap, xF, and polar angle in the charm pair CMS are qualitatively consistent with our measurements. The mean pT of the pairs is equal within errors to that measured in dilepton production at the same energy and mass range.
