    "abstract": "In this work we report on the effects of short-range correlations upon the\nmatrix elements of neutrinoless double beta decay. We focus on the calculation\nof the matrix elements of the neutrino-mass mode of neutrinoless double beta\ndecays of 48Ca and 76Ge. The nuclear-structure components of the calculation,\nthat is the participant nuclear wave functions, have been calculated in the\nshell-model scheme for 48Ca and in the proton-neutron quasiparticle\nrandom-phase approximation (pnQRPA) scheme for 76Ge. We compare the traditional\napproach of using the Jastrow correlation function with the more complete\nscheme of the unitary correlation operator method (UCOM). Our results indicate\nthat the Jastrow method vastly exaggerates the effects of short-range\ncorrelations on the neutrinoless double beta decay nuclear matrix elements.",
