Description
We construct a new parametrization of nuclear PDFs (nPDFs) inspired by short-range correlation (SRC) models, and implement this in a global fit. The SRC motivated parametrization decomposes the nPDFs into a free nucleon component, and a part describing the formation of the bound nucleon pairs. Here, the A-dependence enters only through multiplicative factors describing the number of the nuclear SRC pairs. This new parametrization yields a good description of a wide range of data with a quality comparable to the traditional parameterization. Additionally, the fraction of SRC nucleon pairs appears to rise uniformly with the increasing mass of the nuclei (from about 10% to 30%). We also observe that the number of SRC proton and neutrons are comparable across the full range of nuclei, suggesting that the SRC pairs are proton-neutron combinations in general agreement with current SRC models.
