Measuring the Neutron Spin Asymmetry A1n in the Valence Quark Region in Hall C at Jefferson Lab
The quest to understand how the nucleon spin is decomposed into its constituent quark and gluon spin and orbital angular momentum (OAM) components has been at the forefront of nuclear physics for decades. Due to the non-perturbative nature of Quantum Chromodynamics (QCD) - the theory describing how …

Precision measurement of neutron spin asymmetry An1 at large xBj using CEBAF at 5.7 GeV
Nucleon spin structure has remained one of the key issues of hadronic physics since the 1980's. Among the unsolved questions, the neutron spin structure in the valence quark region (the large Bjorken variable XBj region) is of particular interest. The few data that existed in the large XBj region …

Measurement of Generalized GDH Integrand for the Neutron and 3He at Low Q2
… quarks and gluons, the nuclear forces, and the nucleon mass and structure, still remain in the non-perturbative regime. Dispersive sum rules, based on universal principles, provide a data-driven approach to study the nucleon structure without model-dependencies. Among those sum rules, the well …

Shining a Light on the Nucleus: Photonuclear Measurements from Correlations to Charmonium
… atomic nucleus is comprised of a collection of nucleons (protons and neutrons), which are bound together by the nucleon-nucleon (NN) interaction that originates from Quantum Chromodynamics (QCD). While most nucleons experience the force from the rest of the nucleus as a single net “mean-field” …

Measurement of the Spin Structure Function GD1 of the Deuteron and Its Moments at Low Q2
… the deuteron were used to extract the deuteron's spin structure function <em>g</em>1 as well as the product <em>A</em>1<em>F</em>1 of the virtual photon asymmetry <em>A</em>1 and the unpolarized structure function <em>F</em>1. These extracted quantities, in turn, were used to evaluate three …

Studying the Quark Structure of the Proton in High Energy Proton-Proton Collisions at RHIC
… thesis presents the first measurement of single spin asymmetries from inclusive di-hadron production in polarized proton-proton collisions at Relativistic Heavy Ion Collider. This measurement combines the transversity distribution function and a polarized di-hadron fragmentation function, …
