Searching for flavor dependence in nuclear quark behavior

Understand

The observed correlation between the EMC effect and the contribution of short-range correlations (SRCs) in nuclei suggests that the modification of the quark distributions of bound protons and neutrons might occur within SRCs.

• This raises the possibility that the EMC effect may have an isospin dependence arising from the np dominance of SRCs.
• We discuss previous attempts to test this possibility and perform a new analysis of existing data.
• We find no experimental support for the observation of an isospin dependence of the EMC effect.
