  Renormalization group (RG) methods used to soften Hamiltonians allow
large-scale computational resources to be used to greater advantage in
calculations of nuclear structure and reactions. These RG transformations lower
the effective resolution of the nuclei, which raises questions about how to
calculate and interpret high-momentum transfer probes of nuclear structure.
Such experiments are conventionally explained in terms of short-range
correlations, but these disappear with the evolution to low-momentum scales. We
highlight the important issues and prospects in the context of recent
developments in RG technology, with guidance from the analogous extraction of
parton distributions.
