Abstract

High-energy scattering processes, such as deep inelastic scattering (DIS) and
quasielastic (QE) scattering provide a wealth of information about the
structure of atomic nuclei. The remarkable discovery of the empirical linear
relationship between the slope of the European Muon Collaboration (EMC) effect
in DIS and the short-range-correlation (SRC) scaling factors $a_2$ in QE
kinematics is naturally explained in terms of scale separation in effective
field theory. This explanation has powerful consequences, allowing us to
calculate and predict SRC scaling factors from ab initio low-energy nuclear
theory. We present ab initio calculations of SRC scaling factors for a nucleus
$A$ relative to the deuteron $a_2(A/d)$ and relative to $^3\rm He$ $a_2(A/^3\rm
He)$ in light and medium-mass nuclei. Our framework further predicts that the
EMC effect and SRC scaling factors have minimal or negligible isovector
corrections.
