Large Study of Short-Range Correlations in $^{12}$C(e,e$^{\prime}$pn)
ORAL
Abstract
Experiment E01-015 at JLab Hall A has been investigating electron induced two nucleon emission from carbon with the goal of being sensitive to and studying short-range correlations. The experiment took data from January through April 2005 at a kinematic coverage of Q$^2$ = 2 (GeV/c)$^2$, $x_{B}$ = 1.2 and the missing momentum from $^{12}$C(e,e$^{\prime}$p) reaction ranging 250 to 650 MeV/c. Two high resolution spectrometers were used for e' and p detection in the reaction $^{12}$C(e,e$^{\prime}$pn). The recoiling neutrons were detected by a neutron detector which covered an 81 msr solid angle and consisted of 4 layers of neutron counters, each layer being 10 cm thick. We used a time-of-flight method to reconstruct the neutron momentum. Short-range correlations can be emulated by various two-body effects, so we chose an anti-parallel kinematics with high Q$^2$ at $x_{B}>$1 to minimize meson exchange currents, isobar currents and final-state interactions. Preliminary analysis results from $^{12}$C(e,e$^{\prime}$pn) reaction will be presented.
