Sterile Neutrino Searches
… part of the thesis we explore the sensitivity to sterile neutrinos by using a novel kaon tagging technology: ENUBET, the proposed experiment could decisively test indications from the experiments Neutrino-4 and IceCube. In the second part of the thesis we discuss the current status of sterile …

Sterile neutrino searches in MiniBooNE and MicroBooNE
Tension among recent short baseline neutrino experiments has pointed toward the possible need for the addition of one or more sterile (non-interacting) neutrino states into the existing neutrino oscillation framework. This thesis first presents the motivation for sterile neutrino models by …

Sterile neutrino searches at the Icecube Neutrino Observatory
The IceCube Neutrino Observatory is capable of performing a unique search for sterile neutrinos through the exploitation of a matter enhanced resonant neutrino oscillation phenomena. As atmospheric muon neutrinos pass the dense material within the Earth, neutral current elastic forward scattering …

Solar and Sterile Neutrino Physics with the Raghavan Optical Lattice
The neutrino is, by its nature, an elusive particle that requires massive detectors with small backgrounds to capture a handful of events. Nevertheless, neutrino experiments stand at the heart of the current mysteries of particle physics and astrophysics. These include the origin and size of …

Precise measurement of mixing parameters and sterile neutrino search at Daya Bay
Neutrino oscillation with three active neutrinos has been well established by experiments. However, θ_13 was the least known mixing angle before the Daya Bay reactor neutrino experiment. The Daya Bay experiment uses relative measurement with eight identically-designed antineutrino detectors (ADs) …

Light, Unstable Sterile Neutrinos: Phenomenology, a Search in the IceCube Experiment, and a Global Picture
Longstanding anomalies in neutrino oscillation experiments point to the existence of a fourth, hypothetical neutrino: the sterile neutrino. Global fits to a sterile neutrino model find a strong preference for such a model over the massive neutrino Standard Model. However, the fit results suffer …

Observation of Reactor Antineutrinos with the CHANDLER Detector
… anomalies hint at the possible existence of a sterile neutrino. Several experiments have been searching for the sterile neutrino, but none can claim either its discovery or fully rule it out. To test the sterile neutrino hypothesis, we search for short baseline oscillations using antineutrinos …

Precision Search for Muon Antineutrino Disappearance Oscillations Using a Dual Baseline Technique
A search for short baseline muon antineutrino disappearance with the SciBooNE and MiniBooNE experiments at Fermi National Accelerator Laboratory in Batavia, Illinois is presented. Short baseline muon antineutrino disappearance measurements help constrain sterile neutrino models. The two detectors …

X-ray searches for decaying sterile neutrinos with the Micro-X and XQC sounding rockets
… candidate. One proposed particle is the sterile neutrino, a counterpart of the observed active neutrino with right-handed chirality. A recent detection of an unidentified X-ray emission line has been suggested as a possible signal of sterile neutrino decay, but requires more observations …

Neutrinos, neurons and neutron stars : applications of new statistical and analysis techniques to particle and astrophysics
… data from particle and astrophysics experiments. Sterile neutrinos are a hypothetical fourth kind of neutrino, which are motivated by anomalies observed in various short base-line neutrino experiments. These experiments have published results that are not mutually compatible. This thesis presents …

Searches for new physics at MiniBooNE : sterile neutrinos and mixing freedom
… different from that allowed by standard, three neutrino oscillations, as determined by solar and atmospheric neutrino experiments. This search was motivated by the LSND experimental observation of an excess of F/e events in a 1,1 beam which was found compatible with two-neutrino oscillations at …

Oscillations and Sterile Neutrinos
In this work I aim to introduce neutrino physics from its fairly mundane beginnings all the way up to the discovery of neutrino oscillations, the latest detectors and theoretical extensions to current models. When viewed individually, many of the detector methods and theories for oscillation seem …

Ion Source Development for IsoDAR and Multi-Messenger Astrophysics with KamLAND
Neutrinos can answer many open questions in physics. Doing so will require developing new technology, effective collaboration between experiments, and using existing data in new ways. This work presents contributions to these efforts with the IsoDAR, SNEWS, and KamLAND collaborations. The results …

Through Iron & Ice: Searching for Sterile Neutrinos at the IceCube Neutrino Observatory
… the rapid progression in our understanding of neutrinos over the last half century, much is left unknown about their properties. This leaves neutrinos as the most promising portal for Beyond Standard Model (BSM) physics, and neutrinos have already provided fruitful surprises. A number of …

The HUNTER Experiment: A precision massive-neutrino search based on a laser-cooled atomic source
The HUNTER (Heavy Unseen Neutrinos from Total Energy-momentum Reconstruction) experiment bridges Atomic, Molecular, and Optical (AMO) physics with nuclear physics to search for a long-theorized particle. This elusive particle could provide key insights into the universe's mysteries, including dark …

Sterile neutrinos in cold climates
Measurements of neutrino oscillations at short baselines contain an intriguing set of experimental anomalies that may be suggestive of new physics such as the existence of sterile neutrinos. This three-part thesis presents research directed towards understanding these anomalies and searching for …

The Development of the SNO+ Experiment: Scintillator Timing, Pulse Shape Discrimination, and Sterile Neutrinos
The SNO+ experiment is a multi-purpose neutrino detector which is under construction in the SNOLAB facility in Sudbury, Ontario. SNO+ will search for neutrinoless double beta decay, and will measure low energy solar neutrinos. This thesis will describe three main development activities for the SNO+ …
