“…This supports the idea that the large-x CLAS data were limited by bin-migration effects due to the spectrometer's modest momentum resolution [33]. We do not observe the plateau predicted by the naive SRC model, but explain why the predictions for the ratios in the 3N -SRC regime are not as robust as those for 2N SRC.…”

We present new data probing short-range correlations (SRCs) in nuclei through the measurement of electron scattering off high-momentum nucleons in nuclei. The inclusive 4 He/ 3 He cross section ratio is observed to be both x and Q 2 independent for 1.5 < x < 2, confirming the dominance of two-nucleon short-range correlations. For x > 2, our data support the hypothesis that a previous claim of three-nucleon correlation dominance was an artifact caused by the limited resolution of the measurement. While 3N-SRCs appear to have an important contribution, our data show that isolating 3N-SRCs is significantly more complicated than for 2N-SRCs.

“…A recent reanalysis of the CLAS data (73) shows that this plateau can be the effect of bin migration. Both experiments measured cross sections as a function of the scattered energy of the electron (E ) and converted to x.…”

KeywordsShort-range nucleon correlations, high energy electron nucleus scattering, deep inelastic nuclear scattering, super-fast quarks AbstractNuclear dynamics at short distances is one of the most fascinating to ics of strong interaction physics. The physics of it is closely relate to the understanding the role of the QCD in generating nuclear forc at short distances as well as understanding the dynamics of the supe dense cold nuclear matter relevant to the interior of neutron stars. Wi an emergence of high energy electron and proton beams there is a si nificant recent progress in high energy nuclear scattering experimen aimed at studies of short-range structure of nuclei. This in turn stim ulated new theoretical studies resulting in the observation of sever new phenomena specific to the short range structure of nuclei. In th work we review recent theoretical and experimental progress in studi of short-range correlations in nuclei and their importance for advan ing our understanding of the dynamics of nuclear interactions at sma distances.

“…The generalization to spin-dependent parton structure and to generalized parton distributions [67] is similarly straight forward. EFT could also shed light on whether a plateau of σ A /σ3 He for 2 < x < 3 exists, which is still inconclusive experimentally [10,14,68].…”

Short-Range Correlations and the EMC Effect in Effective Field Theory

et al. 2017

We show that the empirical linear relation between the magnitude of the EMC effect in deep inelastic scattering on nuclei and the short-range correlation scaling factor a_{2} extracted from high-energy quasielastic scattering at x≥1 is a natural consequence of scale separation and derive the relationship using effective field theory. While the scaling factor a_{2} is a ratio of nuclear matrix elements that individually depend on the calculational scheme, we show that the ratio is independent of this choice. We perform Green's function Monte Carlo calculations with both chiral and Argonne-Urbana potentials to verify this and determine the scaling factors for light nuclei. The resulting values for ^{3}He and ^{4}He are in good agreement with experimental values. We also present results for ^{9}Be and ^{12}C extracted from variational Monte Carlo calculations.
