This work determines if the data from Super Bigbite Spectrometer (SBS) experiments in Hall A that have already collected data or plan to collect data can be used to extract information about resonance form factors. These experiments were designed to produce data that gives information about the form factors of protons or neutrons, but sometimes, the interaction of the electron scattering off the nucleon, can leave the nucleon in an excited state. These excited nucleons are called baryon resonances and their form factors are much less well known than that of ground state protons and neutrons. Using Monte Carlo simulations created with GEANT4, this work develops a framework for determining if data from an SBS experiment can give meaningful information about delta resonance form factors. The simulations output ROOT files were analysed using the ROOT data analysis software as well as Python scripts.
