Double-Coincidence $^{12}{\rm C}(e,e'p)$ in a Correlations Dominant Regime

ORAL

Abstract

We performed an experiment to investigate short-range correlations in carbon via a {\it triple-coincidence} $(e,e'pN)$ reaction in Hall A at Jefferson Lab. As a natural consequence of studying the three-body reaction, we collected high-quality {\it double-coincidence} $(e,e'p)$ data, which are presented here. Our kinematics were chosen with $Q^{2} = 2$ (GeV/c)$^{2}$ and $x_{B} > 1$ to provide a regime in which short-range correlations are expected to dominate the initial state; thus, the electrons were scattering primarily off nucleon pairs. The resulting $(e,e'p)$ data were obtained over a high missing-momentum region, $P_{m} \sim 200 - 600$ MeV/c. We present the cross-section data for the bound-state reaction $^{12}$C$(e,e'p)^{11}$B and also for scattering to the continuum from carbon, and compare our results to relativistic theoretical calculations.
