Available in PDF, EPUB and Kindle. Book excerpt: The MiniBooNE experiment was designed to perform a search for Vu --> Ve oscillations in a region of A[delta]sin 2 20very 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 [delta]m 2 ~ 1 eV2 and sin2 20 1%. If confirmed, such oscillation signature could be attributed to the existence of a light, mostly-sterile neutrino, containing small admixtures of weak neutrino eigenstates. In addition to a search for Vu -- Ve oscillations, MiniBooNE has also performed a search for Vu -->Ve oscillations, which provides a test of the LSND two-neutrino oscillation interpretation that is independent of CP or CPT violation assumptions. This dissertation presents the MiniBooNE Vu -->Ve and Vu --> Ve analyses and results, with emphasis on the latter. While the neutrino search excludes the two-neutrino oscillation interpretation of LSND at 98% C.L., the antineutrino search shows an excess of events which is in agreement with the two neutrino Vu -->Ve oscillation interpretation of LSND, and excludes the no oscillations hypothesis at 96% C.L. Even though the neutrino and antineutrino oscillation results from MiniBooNE disagree under the single sterile neutrino oscillation hypothesis, a simple extension to the model to include additional sterile neutrino states and the possibility of CP violation allows for differences between neutrino and antineutrino oscillation signatures. In view of that, the viability of oscillation models with one or two sterile neutrinos is investigated in global fits to MiniBooNE and LSND data, with and without constraints from other oscillation experiments with similar sensitivities to those models. A general search for new physics scenarios which would lead to effective non-unitarity of the standard 3 x 3 neutrino mixing matrix, or mixing freedom, is also performed using neutrino and antineutrino data available from MiniBooNE.
Book Synopsis Testing Explanations of Short Baseline Neutrino Anomalies by : Nicolò Foppiani
Download or read book Testing Explanations of Short Baseline Neutrino Anomalies written by Nicolò Foppiani and published by Springer Nature. This book was released on 2023-11-02 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis, encompassing both theory to experiment, guides the reader in a pedagogical way through the author’s attempts to resolve the mystery of the so-called MiniBooNE anomaly, where unexpected neutrino oscillations were reported, potentially explainable by the existence of light sterile neutrinos, but in contradiction with several null results. Within this context, this thesis reports one of the first analyses searching for an excess of electrons in the MicroBooNE experiment finding no excess of events and narrowing down the possible explanations for the anomaly. Additionally, this thesis explores non-minimal heavy neutral leptons as potential explanations for the MiniBooNE excess. To search for evidence for this particle, the author performs an analysis using data from the T2K experiment, which searched for pairs of electrons using a gas argon time projection. This thesis provides a comprehensive explanation of the MiniBooNE anomaly and test of its possibile explanation with liquid and gas time projection chambers.
Download or read book Ghost Particle written by Alan Chodos and published by MIT Press. This book was released on 2024-09-03 with total page 319 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fascinating story of science in pursuit of the ghostly, ubiquitous subatomic particle—the neutrino. Isaac Asimov is said to have observed of the neutrino: “The only reason scientists suggested its existence was their need to make calculations come out even. And yet the nothing-particle was not a nothing at all.” In fact, as one of the most enigmatic and most populous particles in the universe—about 100 trillion are flying through you every second—the neutrino may hold the clues to some of our deepest cosmic mysteries. In Ghost Particle, Alan Chodos and James Riordon recount the dramatic history of the neutrino—from the initial suggestion that the particle was merely a desperate solution to a puzzle that threatened to undermine the burgeoning field of particle physics to its modern role in illuminating the universe via neutrino telescopes. Alan Chodos and James Riordon are deft and engaging guides as they conduct readers through the experiences of intrepid scientists and the challenges they faced, and continue to face, in their search for the ghostly neutrino. Along the way, the authors provide expert insight into the significance of neutrino research from the particle’s first, momentous discovery to recent, revolutionary advances in neutrino detection and astronomy. Chodos and Riordon describe how neutrinos may soon provide clues to some of the biggest questions we encounter today, including how to understand the dark matter that makes up most of the universe—and why anything exists in the universe at all.

Book excerpt: The latest results from MiniBooNE, the short baseline neutrino experiment operating on the 8 GeV booster's neutrino beam line (the BNB) at Fermilab, are discussed. The standard three active generation model of neutrino oscillations is now grounded firmly by experimental data. Studying the properties of neutrinos at the few percent level and below may uncover new properties of neutrinos and their oscillations and provide a path to physics beyond the standard neutrino model.

Book Synopsis Search for Sterile Neutrinos with the MINOS Long-Baseline Experiment by : Ashley Michael Timmons
Download or read book Search for Sterile Neutrinos with the MINOS Long-Baseline Experiment written by Ashley Michael Timmons and published by Springer. This book was released on 2017-08-10 with total page 177 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis highlights data from MINOS, a long-baseline accelerator neutrino experiment, and details one of the most sensitive searches for the sterile neutrino ever made. Further, it presents a new analysis paradigm to enable this measurement and a comprehensive study of the myriad systematic uncertainties involved in a search for a few-percent effect, while also rigorously investigating the statistical interpretation of the findings in the context of a sterile neutrino model. Among the scientific community, this analysis was quickly recognized as a foundational measurement in light of which all previous evidence for the sterile neutrino must now be (re)interpreted. The existence of sterile neutrinos has long been one of the key questions in the field. Not only are they a central component in many theories of new physics, but a number of past experiments have yielded results consistent with their existence. Nonetheless, they remain controversial: the interpretation of the data showing evidence for these sterile neutrinos is hotly debated.

Book Synopsis Particle Physics: Ideas and Recent Developments by : Jean-Jacques Aubert
Download or read book Particle Physics: Ideas and Recent Developments written by Jean-Jacques Aubert and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 518 pages. Available in PDF, EPUB and Kindle. Book excerpt: For more than 25 years the Standard Model of particle physics has withstood the confrontation with experimental results of increasing precision, but this does not imply that the Standard Model can answer all questions about the ultimate constituents of nature. This book presents a critical examination of the latest experimental results and confronts them with the predictions of the Standard Model. Besides discussions of accelerator results from LEP, HERA and the TEVATRON, attention is paid to the unresolved problems of neutrino oscillations, CP violation, dark matter and cosmology. New theoretical ideas are also analyzed in order to explore possible extensions of the standard model. Realistic plans for future accelerators are presented and their physics potential is discussed, paving the way for the next generation of particle physics experiments.

Download or read book Accelerator-Produced Dark Matter Search Using MiniBooNE. written by and published by . This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Cosmology observations indicate that our universe is composed of 25% dark matter (DM), yet we know little about its microscopic properties. Whereas the gravitational interaction of DM is well understood, its interaction with the Standard Model is not. Direct detection experiments, the current standard, have a nuclear recoil interaction, low-mass sensitivity edge of order 1 GeV. To detect DM with mass below 1 GeV, either the sensitivity of the experiments needs to be improved or use of accelerators producing boosted low-mass DM are needed. Using neutrino detectors to search for low-mass DM is logical due to the similarity of the DM and $\nu$ signatures in the detector. The MiniBooNE experiment, located at Fermilab on the Booster Neutrino Beamline, has produced the world's largest collection of $\nu$ and $\bar{\nu}$ samples and is already well understood, making it desirable to search for accelerator-produced boosted low-mass DM. A search for DM produced by 8.9 GeV/c protons hitting a steel beamdump has finished, collecting $1.86\times10^{20} \mathrm{POT}$. Analysis techniques along with predicted sensitivity will be presented.
