QCD sum rules provide a constraint on hadronic models for this correlator. This constraint is discussed for the case of finite nuclear density concerning the longitudinal as well as the transverse part of the current-current correlator at finite three-momentum.RevTeX, 38 pages, 5 figuresNuclear TheoryHigh Energy Physics - Phenomenologytext
