We analyze the longitudinal structure of nuclei as described in the context of nuclear parton distribution functions (nPDFs). Such a description uses the language of QCD factorization theorems, in analogy to the parton distributions (PDFs) of free protons. We focus on the high-x region and introduce a novel phenomenological nPDF parametrization inspired by the short range correlation (SRC) models. This allows us for extracting of "traditional" nPDFs but also of the universal effective distribution of quarks and gluons inside the correlated nucleon pairs, and their nucleus-specific fractions.
