/Abstract/

Short-range correlations (SRCs) are the primary source of the high 
momentum components of the nucleon momentum distribution in nuclei.  Due 
to the highly localized feature of these correlated nucleons, the 
high-momentum tails from light to heavy nuclei reveal very similar 
distributions when their momenta are above the Fermi momentum.  With 
measurements of inclusive electron scattering on different nuclei in the 
quasi-elastic region, we are able to study the two- and three- nucleon 
correlations (2N-SRC and 3N-SRC), by taking the cross section ratios of 
heavy nuclei to light nuclei, such as Deuteron or He3. Clear and 
consistent signatures of 2N-SRC have been observed  at SLAC  and more 
recently in Halls B and Hall C. However, there is still no clear 
evidence of the 3N-SRC because the Hall-B and Hall-C results yield 
different results for x>2, the region where 3N-SRCs are expected to 
dominate. The most recent experiment in Hall A, E08014, aimed to perform 
a more precise measurement on the 3N-SRC. In this talk, I will briefly 
introduce the SRCs, previous measurements and show some new results of 
the E08-014 experiment, followed by some discussion of remaining questions.
