    "abstract": "We analyze the structure of correlations among more than two quantum systems.\nWe introduce a classification of correlations based on the concept of\nnon-separability, which is different {\\em a priori} from the concept of\nentanglement. Generalizing a result of Svetlichny [Phys. Rev. D {\\bf 35} (1987)\n3066] on 3-particle correlations, we find an inequality for $n$-particle\ncorrelations that holds under the most general separability condition and that\nis violated by some quantum-mechanical states.",
