  Recent experimental data on inclusive and exclusive lepton and hadron
scattering off nuclei have renewed the interest in theoretical and experimental
studies of Short Range Correlations (SRC), due to the relevant impact they may
have not only on the structure of ordinary nuclei but on the structure of
hadronic matter at high densities as well. One of the ultimate aim of these
studies is the determination of the probability of two- and three-nucleon
correlations in nuclei. To this end, we have studied the possibility to extract
these probabilities from a novel analysis of inclusive A(e, e')X processes in
terms of relativistic scaling variables which incorporate effects from two- and
three-nucleon SRC, with a resulting scaling function strictly related to
longitudinal momentum distributions; such an approach led to a satisfactory
explanation of the cross section ratios recently found at JLab and interpreted
as strong evidence of SRC in nuclei.
