    "abstract": "The two-nucleon spectral function in nuclear matter is studied using\nCorrelated Basis Function perturbation theory, including central and tensor\ncorrelations produceded by a realistic hamiltonian. The factorization property\nof the two-nucleon momentum distribution into the product of the two single\nnucleon distributions shows up in an analogous property of the spectral\nfunction. The correlated model yields a two-hole contribution quenched whith\nrespect to Fermi gas model, while the peaks acquire a quasiparticle width that\nvanishes as the two momenta approach $k_F$. In addition, three-hole\none-particle and more complicated intermediate states give rise to a\nbackground, spread out in energy and absent in the uncorrelated models. The\npossible connections with one- and two-nucleon emission processes are briefly\ndiscussed.",
