Description
The deuteron, as the simplest neutron-proton bound state, provides a unique opportunity as a starting point to study short-range nuclear dynamics and nucleon-nucleon interactions at high momentum transfer without any complications which usually arise from heavy atoms. At large four-momentum transfer ($Q^2 \approx 4.5~\mathrm{GeV}^2$) and Bjorken $x > 1$, E12-10-003 experiment which was conducted in Jefferson Lab experiment investigates exclusive deuteron electro-disintegration in the reaction $^2\mathrm{H}(e,e'p)n$. The reaction mechanism includes contributions from Plane Wave Impulse Approximation (PWIA), Final State Interaction (FSI), Isobar Configuration (IC) and Meson Exchange Current (MEC).
This work presents the cross-section analysis of the experimental data using theoretical and PWIA for a set of missing momenta ($P_{m}$) settings ranging from approximately 120 to 900 MeV/c, at different neutron-recoil angle ($\theta_{nq}$).
The measured cross-sections are studied as functions of missing momenta and neutron recoil angle in order to investigate the evolution of the reaction mechanism over a broad kinematic range. Comparisons between experimental data and theoretical models provide insight into the role of short-range nucleon interactions, the effects of final-state interactions, and the transition from low to high-momentum nuclear dynamics in the deuteron at large momentum transfer.
