Recent experiments and many-body calculations indicate that approximately 20% of the nucleons in medium and heavy nuclei (A≥12)are part of short-range correlated (SRC)primarily neutron-proton (np)pairs. We find that using chiral dynamics to account for the formation of np pairs due to the effects of iterated and irreducible two-pion exchange leads to values consistent with the 20% level. We further apply chiral dynamics to study how these correlations influence the calculations of nuclear charge radii, that traditionally truncate their effect, to find that they are capable of introducing non-negligible effects.
