Abstract

This dissertation investigates precision measurements of neutrino interactions within the framework of the Standard Model and explores potential extensions beyond it. Neutrinos, often referred to as ghostly particles due to their weak interactions and elusive nature, have long been a frontier in particle physics. Through detailed theoretical modeling and comparison with experimental data, this work focuses on improving our understanding of neutrino-nucleon cross-sections, nucleon form factors, and generalized neutrino interactions. The study begins with a comprehensive examination of the role of vector and axial-vector form factors in neutrino-nucleon scattering and their impact on the interpretation of neutrino oscillation data from experiments like NOvA and DUNE. Special attention is given to the low-energy behavior of these form factors, which is essential for accurate cross-section predictions in the few-GeV energy range, where many modern neutrino oscillation experiments operate. The dissertation also investigates how these precision measurements can constrain or reveal potential new physics, particularly in the context of non-standard neutrino interactions. Ultimately, this work aims to provide both theoretical advancements and practical insights that will aid the next generation of neutrino experiments in their quest to deepen our understanding of the fundamental forces and particles that make up the universe.
