Many-Body Correlation Effects on the <i>x</i><sub>Bjorken</sub>-Dependence of Cross Section Ratios off Nuclei for 1 < <i>x</i><sub>Bjorken</sub> < 2

Many-body correlations in nuclei determine the behavior of Deep-Inelastic-Scattering (DIS) and Quasi-Elastic Scattering (QES) cross section ratios off heavy over light especially for xBjorken > 1, obtained at Jefferson Lab. They can be described terms quark-cluster formation due to wave-function overlapping, manifesting itself when momentum transfer is high so that partonic degrees freedom are resolved. In clusters (correlated nucleons) quark gluon distributions softer than single nucleons extend 1. The cluster probabilities computed using a network-defining algorithm which initial nucleon density either standard Woods-Saxon or input from lower energy data while critical radius merging an adjustable parameter. exact choice depends on specific nucleus it anti-correlated rescaling needed bound nucleons. calculations show there strong dependence agreement with four-body explain experimental results even range 1 < 2. exponents parton high-order weak.
