Electron Scattering From A High Momentum Neutron In Deuterium, Alexei V. Klimenko
Electron Scattering From A High Momentum Neutron In Deuterium, Alexei V. Klimenko
Physics Theses & Dissertations
The deuterium nucleus is a system of two nucleons (proton and neutron) bound together. The configuration of the system is described by a quantum-mechanical wave function and the state of the nucleons at a given time is not known a priori. However, by detecting a backward going proton of moderate momentum in coincidence with a reaction taking place on the neutron in deuterium, the initial state of that neutron can be inferred if we assume that the proton was a spectator to the reaction. This method, known as spectator tagging, was used to study the electron scattering from high-momentum neutrons …

Spin structure functions of the nucleon in the region of large x and small to moderate Q2 continue to be of high current interest. The first moment of the spin structure function g1, Γ1, goes through a rapid transition from the photon point (Q2 = 0), where it is constrained by the Gerasimov-Drell-Hearn sum rule, to the deep inelastic limit where it is sensitive to the nucleon spin fraction carried by quarks. The interesting behavior in the transition region is dominated by baryon resonance excitations. We concluded an experiment to measure these observables …

Some Aspects Of Deeply Virtual Compton Scattering, Elena Kuchina
Physics Theses & Dissertations
We consider different aspects of the virtual Compton amplitude in QCD on two examples: small-x physics accessible in the Regge regime and twist-3 approximation in the description of DVCS through the general parton distributions. Using this model, we give an estimate for the cross section of deeply virtual Compton scattering for the kinematics of CEBAF at Jefferson Lab.
