A Study Of Systematic Uncertainties For A Photon-Like Low Energy Excess Search At Microboone, Gray Yarbrough Aug 2021

A Study Of Systematic Uncertainties For A Photon-Like Low Energy Excess Search At Microboone, Gray Yarbrough

Doctoral Dissertations

The premise of this dissertation is the study of and reduction of systematic uncertainties in the MicroBooNE experiment at the Fermi National Accelerator Laboratory. MicroBooNE is a short-baseline oscillation experiment using the innovative liquid argon time projection chamber technology to study, with unprecedented detail, neutrino interactions. The primary goal of MicroBooNE is the investigation of the MiniBooNE low energy excess (LEE) of electron neutrino events, a result which raised fundamental questions on the existence of sterile neutrinos with broad implications to the field of particle physics. The principal study of this dissertation is a study of systematics as part of …


Daq Software Contributions, Absolute Scale Energy Calibration And Background Evaluation For The Nova Experiment At Fermilab, Eric Flumerfelt Aug 2015

Daq Software Contributions, Absolute Scale Energy Calibration And Background Evaluation For The Nova Experiment At Fermilab, Eric Flumerfelt

Doctoral Dissertations

The NOvA (NuMI Off-axis νe [nu_e] Appearance) Experiment is a long-baseline accelerator neutrino experiment currently in its second year of operations. NOvA uses the Neutrinos from the Main Injector (NuMI) beam at Fermilab, and there are two main off-axis detectors: a Near Detector at Fermilab and a Far Detector 810 km away at Ash River, MN. The work reported herein is in support of the NOvA Experiment, through contributions to the development of data acquisition software, providing an accurate, absolute-scale energy calibration for electromagnetic showers in NOvA detector elements, crucial to the primary electron neutrino search, and through an …
