Abstract Details

2019, Doctor of Philosophy (PhD), Ohio University, Physics and Astronomy (Arts and Sciences).
The work presented in this thesis is based on the g10 experiment performed at the Hall B of the Jefferson Laboratory, where tagged photons with beam energies between 0.8 and 3.5 GeV were incident on a deuterium target. With three final state particles detected (two charged pions and a deuteron), various reaction channels can be studied. This work focuses on three of many possible processes using the same reaction sample:

γ d → ρ d → π+π- d

γ d → ω d → π+π- d (π0)

γ d → NΔ ≡ d∗π±→ π+π- d.

The first two channels deal with the photoproduction of vector mesons. Differential cross sections as a function of the momentum transfer, t, are calculated for various photon energies. Using a phenomenological model based on the theory of Vector Meson Dominance, the Vector Meson-Nucleon scattering cross section (σVN) were extracted for ρ and ω. The third reaction, on the other hand primarily focuses on the production of possible dibaryon resonances. This work establishes the possibility of three dibaryonic charge states (possible NΔ configuration) and presents a preliminary differential cross section for one of the charged states.
