Abstract
We report the results of a calculation of the nuclear matrix element of neutrinoless double- decay of , carried out taking into account nucleon-nucleon correlations in both coordinate and spin space. Our numerical results, obtained using nuclear matter correlation functions, suggest that inclusion of correlations may lead to a % decrease of the matrix element, with respect to the shell-model prediction. This conclusion is supported by the results of an independent calculation, in which correlation effects are taken into account using the spectroscopic factors of , obtained from an ab initio many-body approach, to renormalize the shell-model states.
