Short range correlations in nuclear matter at equilibrium

In this paper the effects of short-range correlations on the single-particle spectral functions, the occupation probabilities and the pair distribution functions of nuclear matter are studied. Calculations have been performed in the framework of Green functions and variational theories, whose main characteristics are briefly discussed. Semirealistic interactions derived from the Reid's soft-core interaction have been used. The momentum distribution is calculated in several ways showing in all cases a depletion of about 13% around normal nuclear matter densities. The effects of the statistical and short-range correlations on the different pair distribution functions are compared
