The ongoing nuclear physics program at Jefferson Lab has been instrumental in advancing our understanding of the structure of the nucleus along with its constituent nucleons. In my talk, I will begin with a brief outline of electron scattering, followed by an overview of two recent experiments performed at Jefferson Lab, the MARATHON and π0 SIDIS experiments. The MARATHON experiment measured the Fn 2 /Fp 2 structure function ratio at high x along with the EMCeffect of the mirror nuclei, Helium-3 and Tritium, using inclusive deep inelastic scattering. The π0 SIDIS experiment performed semi-inclusive deep inelastic scattering, utilizing the newly constructed Neutral Particle Spectrometer (NPS), to detect π0 events in coincidence with the scattered electron (e−) in the High Momentum Spectrometer in Hall C. Both experiments aim to improve our understanding of nucleon structure and I will highlight recent results from the MARATHON experiment while discussing the anticipated impact of the π0 SIDIS experiment. Finally, I will look towards the future, briefly summarizing my future experimental program, which includes studying the two-photon effect (TPE) in deep inelastic scattering through transverse single-spin asymmetries, as well as measuring the size of the TPE in elastic scattering.
