Query: Scaling within the Spectral Function approach   Scaling features of the nuclear electromagnetic response functions unveil
aspects of nuclear dynamics that are crucial for interpretating neutrino- and
electron-scattering data. In the large momentum-transfer regime, the
nucleon-density response function defines a universal scaling function, which
is independent of the nature of the probe. In this work, we analyze the
nucleon-density response function of $^{12}$C, neglecting collective
excitations. We employ particle and hole spectral functions obtained within two
distinct many-body methods, both widely used to describe electroweak reactions
in nuclei. We show that the two approaches provide compatible nucleon-density
scaling functions that for large momentum transfers satisfy first-kind scaling.
Both methods yield scaling functions characterized by an asymmetric shape,
although less pronounced than that of experimental scaling functions. This
asymmetry, only mildly affected by final state interactions, is mostly due to
nucleon-nucleon correlations, encoded in the continuum component of the hole
SF.
