  Title: “Three Nucleons Short Range Correlations Studies in Inclusive
  Electron Scattering”

  Abstract:  Short range correlations (SRC) can be studied in inclusive
  quasi-elastic electron scattering as the ratio of the cross sections
  of heavy to light nuclei provides a measure two-nucleon SRC (2N-SRC)
  and three-nucleon
  SRC (3N-SRC) in the region of 1 < xbj < 2 and 2 < xbj < 3 regions,
  respectively. Recent experiments at Je_erson Lab con_rmed the early
  measurements while including a wider range of nuclei and an extension
  into the 3N-SRC region. Measurements in the 3N region, however, su_er
  from poor experimental precision. Meanwhile, an exclusive measurement,
  also at Je_erson Lab, showed a strong isospin dependence of 2N-SRCs.
  Experiment E08014 was designed to study the onset of 3N-SRC for xbj >
  2 with better accuracy, and to examine the isospin dependence of SRCs
  in inclusive scattering using the calcium isotopes. E08014 ran in Hall
  A in 2011 and we will briey present the experimental setup along with
  status of the data analysis followed by a discussion of the
  preliminary results.
