This thesis explores the electron-neutrino and antineutrino cross section on argon using the MicroBooNE liquid argon time projection chamber detector. With only a handful of electron neutrino cross section measurements in the hundred MeV to GeV range to date and only one of them on argon as the target nucleus: the result from the ArgoNeuT experiment, there is a need for new, large statistics, electron-neutrino cross section measurements. The precise knowledge of the electron neutrino cross section is fundamental for tests of lepton universality, making meaningful interpretations of neutrino oscillations and beyond the Standard Model search experiments involving electron neutrinos. Moreover, the appearance of electron neutrinos in a beam of predominantly muon neutrinos is the key signature in searches for sterile neutrinos in short-baseline experiments and measurements of Charge-Parity violation in long-baseline oscillation experiments. The measurements in this thesis utilize the NuMI neutrino beamline which is highly off-axis to the MicroBooNE detector but provides a rich source of electron-neutrinos. Critical to the measurement of the cross section is a detailed understanding of the flux of neutrinos at MicroBooNE and the uncertainties associated with it. The neutrino flux prediction tools used for the on-axis NuMI experiments are described and studied in detail for their implementation in the case of MicroBooNE. These tools will form the foundation for many future measurements using the NuMI beam at MicroBooNE. With the use of argon as a target for studying neutrino interactions, the large size of the nucleus introduces nuclear effects which impact the kinematics and multiplicities of the particles produced in the initial interaction. Such effects are complicated to model and are currently an active area of research with various models and neutrino generators available. The measurements in this thesis compare the electron-neutrino argon cross section to several neutrino generators with differing physics models. These comparisons provide important information in the modelling of neutrino interactions with nuclei such as argon. The target audience for this thesis is aimed at particle physics graduate students, particularly in the field of neutrino physics working with noble element time-projection chambers.

Results from neutrino oscillation experiments in the last ten years have revolutionized the field of neutrino physics. While the overall oscillation picture for three neutrinos is now well established and precision measurements of the oscillation parameters are underway, crucial issues remain. In particular, the hierarchy of the neutrino masses, the structure of the neutrino mixing matrix, and, above all, CP violation in the neutrino sector are the primary experimental challenges in upcoming years. A program that utilizes the newly commissioned NuMI neutrino beamline, and its planned upgrades, together with a high-performance, large-mass detector will be in an excellent position to provide decisive answers to these key neutrino physics questions. A Liquid Argon time projection chamber (LArTPC) [2], which combines fine-grained tracking, total absorption calorimetry, and scalability, is well matched for this physics program. The few-millimeter-scale spatial granularity of a LArTPC combined with dE/dx measurements make it a powerful detector for neutrino oscillation physics. Scans of simulated event samples, both directed and blind, have shown that electron identification in {nu}{sub e} charged current interactions can be maintained at an efficiency of 80%. Backgrounds for {nu}{sub e} appearance searches from neutral current events with a {pi}{sup 0} are reduced well below the {approx} 0.5-1.0% {nu}{sub e} contamination of the {nu}{sub {mu}} beam [3]. While the ICARUS collaboration has pioneered this technology and shown its feasibility with successful operation of the T600 (600-ton) LArTPC [4], a detector for off-axis, long-baseline neutrino physics must be many times more massive to compensate for the low event rates. We have a baseline concept [5] based on the ICARUS wire plane structure and commercial methods of argon purification and housed in an industrial liquefied-natural-gas tank. Fifteen to fifty kton liquid argon capacity tanks have been considered. A very preliminary cost estimate for a 50-kton detector is $100M (unloaded) [6]. Continuing R & D will emphasize those issues pertaining to implementation of this very large scale liquid argon detector concept. Key hardware issues are achievement and maintenance of argon purity in the environment of an industrial tank, the assembly of very large electrode planes, and the signal quality obtained from readout electrodes with very long wires. Key data processing issues include an initial focus on rejection of cosmic rays for a surface experiment. Efforts are underway at Fermilab and a small number of universities in the US and Canada to address these issues with the goal of embarking on the construction of industrial-scale prototypes within one year. One such prototype could be deployed in the MiniBooNE beamline or in the NuMI surface building where neutrino interactions could be observed. These efforts are complementary to efforts around the world that include US participation, such as the construction of a LArTPC for the 2-km detector location at T2K [7]. The 2005 APS neutrino study [1] recommendations recognize that ''The development of new technologies will be essential for further advances in neutrino physics''. In a recent talk to EPP2010, Fermilab director P. Oddone, discussing the Fermilab program, states on his slides: ''We want to start a long term R & D program towards massive totally active liquid Argon detectors for extensions of NOvA''. [8]. As such, we are poised to enlarge our R & D efforts to realize the promise of a large liquid argon detector for neutrino physics.

Liquid Argon Time Projection Chambers (LArTPCs) represent one of the most widely utilized neutrino detection techniques in neutrino experiments, for instance, in the Short Baseline Neutrino (SBN) program and the future large-scale LArTPC: Deep Underground Neutrino Experiment (DUNE). The high-end technique, facilitating excellent spatial and calorimetric reconstruction resolution, also enables testing exotic Beyond Standard Model (BSM) theories, such as baryon number violation (BNV) processes (e.g., proton-decay, neutron-antineutron oscillation). At the same time, Machine Learning (ML) techniques have demonstrated their ubiquitous use in recent decades; ML techniques have also become some of the most powerful tools in high-energy physics (HEP) analyses. Furthermore, the development of algorithms to cater to the needs of problems in HEP (i.e., triggering, reconstruction, improving sensitivity, etc.) has also become an active area of research. By developing a combined approach using Convolutional Neural Network (CNN) and Boosted Decision Tree (BDT) techniques, the sensitivity of neutron-antineutron oscillation in DUNE is evaluated for a projected exposure of 400kton⋅ years.

The Deep Underground Neutrino Experiment (DUNE) will be a world-class neutrino observatory and nucleon decay detector designed to answer fundamental questions about elementary particles and their role in the universe. My dissertation centers on the implementation of technologies used to detect scintillation photon signals in LAr in the context of the DUNE single-phase far detector module design, and features direct contributions to the Photon detection systems (PDS) deployed in the ProtoDUNE Large-Volume Liquid Argon Time Projection Chamber (LArTPC) prototype. The PDS is needed for non-beam event timing, such as atmospheric neutrinos, proton decay, and supernova detection. The PDS also provides a prompt signal for microsecond event time determination, which improves the LArTPC's spatial localization, enables accurate ionization-signal-attenuation, and even provides calorimetry.The focus of my thesis is using scintillation light detection in a large-volume LArTPC, to understand the total energy deposition and how we can use this information to understand the underlying physics of neutrino oscillations, the neutrino mass hierarchy, CP-Violation, supernova detection, and searches for nucleon decay. Our collaborative achievements have included understanding test-beam data for different particle types at momenta 0.3 - 7 GeV/c. Further, it has been key in validating a full-scale DUNE detector technology and engineering components, continuing to demonstrate its long-term operational stability of all detector components.The analysis of ProtoDUNE, including my core thesis work on Scintillation Photon Detection in LArTPC, exposed to a multi-GeV charged particle beam, is shown in our published paper [1]. The construction, installation, and operation of DUNE's first full-scale prototype, ProtoDUNE, detector is described in our technical paper [2].
