Experimental evidence for isospin dependence in the EMC effect

The observed correlation between the EMC effect and the relative contribution of SRCs in nuclei, combined with the observed np-dominance of high-momentum nucleon pairs, raises the question of whether the isospin dependence of SRCs yields an isospin-dependent EMC effect. The physics behind the EMC-SRC correlation, be it a common origin of both effects or SRCs as a source of the EMC effect, determines to what extend np-dominance of SRCs yields an isospin-dependent EMC effect. We examine existing data to look for observables that might be able to distinguish between different explanations for the observed correlation and address the question of isospin dependence in the EMC effect.
