SRC Scaling at Low xB and the Mean-Field to SRC Transition
ORAL
Abstract
High momentum nucleons in Short Range Correlations (SRC) cannot be described by mean-field spectral functions and it is difficult to build a picture that describes both phenomena. Most SRC analyses look at events at high-xB to reduce the effect of Final State Interactions (FSI) and inelastic scattering, but this also cuts out the mean field contribution. This means we have no way of seeing how the nucleon momentum distribution evolves over the full momentum range from mean-field to SRC. The analysis presented here achieves a cross section ratio that spans a wide momentum range by relaxing the high-xB cut while keeping strict missing mass cuts on the detected electron and proton to mitigate background scattering mechanisms. Now that our cross section ratios cover a new kinematic range, we can begin to bridge the gap between mean-field and SRC nucleons.
