Query: Clustering in the Las Campanas Distant Cluster Survey   We utilize a sample of galaxy clusters at 0.35<z<0.6 drawn from the Las
Campanas Distant Cluster Survey (LCDCS) to provide the first non-local
constraint on the cluster-cluster spatial correlation function. The LCDCS
catalog, which covers an effective area of 69 square degrees, contains over
1000 cluster candidates. Estimates of the redshift and velocity dispersion
exist for all candidates, which enables construction of statistically
completed, volume-limited subsamples. In this analysis we measure the angular
correlation function for four such subsamples at z~0.5. After correcting for
contamination, we then derive spatial correlation lengths via Limber inversion.
We find that the resulting correlation lengths depend upon mass, as
parameterized by the mean cluster separation, in a manner that is consistent
with both local observations and CDM predictions for the clustering strength at
z=0.5.
