Abstract
We calculate the cross-correlation function between the eigenvalues of two random hermitian matrices taken from separate gaussian ensembles. In the limit of large matrices the correlation, when suitably smoothe d, reproduces a previous result obtained by diagrammatic methods. Unli ke previous results, however, this unsmoothed correlation function may be studied at short distances.
