Description
Short Range Correlations (SRCs) are a feature of the internal structure of all
types of nuclei. Characterized by their relative and center of mass momenta,
SRC pairs have been well studied with quasi-elastic electron scattering
experiments. The reliance on electron scattering however, makes it difficult
to assess the influence of reaction effects and final state interactions on
what has been learned so far about SRCs. For that reason, the Hall D Short
Range Correlations Experiment was conducted at Jefferson Lab in Fall 2021
using a real photon beam incident on nuclear targets to explore SRCs
through various photoproduction channels, providing insight into different
kinematic regions and different final states. Our preliminary analysis shows
that the predictions of Generalized Contact Formalism (GCF) work well for
photoproduction. In my analysis, I have considered (γ p ,ρ⁰ p)
photoproduction from protons participating in SRCs as a tool for testing the
correlations’ isospin structure, in order to verify the predominance of np-
pairing observed in electron scattering. Preliminary results of testing np-pair
dominance along with comparisons to GCF will be presented in this talk.
