Query: Extracing the number of short-range corerlated nucleon pairs from
  inclusive electron scattering data   The extraction of the relative abundances of short-range correlated (SRC)
nucleon pairs from inclusive electron scattering is studied using the
generalized contact formalism (GCF) with several nuclear interaction models.
GCF calculations can reproduce the observed scaling of the cross-section ratios
for nuclei relative to deuterium at high-$x_B$ and large-$Q^2$,
$a_2=(\sigma_A/A)/(\sigma_d/2)$. In the non-relativistic instant-form
formulation, the calculation is very sensitive to the model parameters and only
reproduces the data using parameters that are inconsistent with ab-initio
many-body calculations. Using a light-cone GCF formulation significantly
decreases this sensitivity and improves the agreement with ab-initio
calculations. The ratio of similar mass isotopes, such as $^{40}$Ca and
$^{48}$Ca, should be sensitive to the nuclear asymmetry dependence of SRCs, but
is found to also be sensitive to low-energy nuclear structure. Thus the
empirical association of SRC pair abundances with the measured $a_2$ values is
only accurate to about $20\%$. Improving this will require cross-section
calculations that reproduce the data while properly accounting for both nuclear
structure and relativistic effects.
