Download or read book A Search for Muon Neutrino to Electron Neutrino Oscillations in the MINOS Experiment written by Juan Pedro Ochoa-Ricoux and published by Springer Science & Business Media. This book was released on 2011-04-11 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: The centerpiece of the thesis is the search for muon neutrino to electron neutrino oscillations which would indicate a non-zero mixing angle between the first and third neutrino generations (θ13), currently the “holy grail” of neutrino physics. The optimal extraction of the electron neutrino oscillation signal is based on the novel “library event matching” (LEM) method which Ochoa developed and implemented together with colleagues at Caltech and at Cambridge, which improves MINOS’ (Main Injector Neutrino Oscillator Search) reach for establishing an oscillation signal over any other method. LEM will now be the basis for MINOS’ final results, and will likely keep MINOS at the forefront of this field until it completes its data taking in 2011. Ochoa and his colleagues also developed the successful plan to run MINOS with a beam tuned for antineutrinos, to make a sensitive test of CPT symmetry by comparing the inter-generational mass splitting for neutrinos and antineutrinos. Ochoa’s in-depth, creative approach to the solution of a variety of complex experimental problems is an outstanding example for graduate students and longtime practitioners of experimental physics alike. Some of the most exciting results in this field to emerge in the near future may find their foundations in this thesis.

This book was released on 2014-09-23 with total page 185 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a major step forward in experimentally understanding the behavior of muon neutrinos and antineutrinos. Apart from providing the world’s first measurement of these interactions in a mostly unexplored energy region, the data presented advances the neutrino community’s preparedness to search for an asymmetry between matter and anti-matter that may very well provide the physical mechanism for the existence of our universe. The details of these measurements are preceded by brief summaries of the history of the neutrino, the phenomenon of neutrino oscillations, and a description of their interactions. Also provided are details of the experimental setup for the measurements and the muon antineutrino cross-section measurement which motivates the need for dedicated in situ background constraints. The world’s first measurement of the neutrino component of an antineutrino beam using a non-magnetized detector, as well as other crucial background constraints, are also presented in the book. By exploiting correlated systematic uncertainties, combined measurements of the muon neutrino and antineutrino cross sections described in the book maximize the precision of the extracted information from both results.

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.
Download or read book Neutrino Astrophysics written by John N. Bahcall and published by Cambridge University Press. This book was released on 1989-07-28 with total page 596 pages. Available in PDF, EPUB and Kindle. Book excerpt: This authoritative text provides a lively, thought-provoking and informative summary of neutrino astrophysics. Neutrino astronomy is being revolutionized by the availability of new observational facilities. Theoretical work in astrophysics and in particle physics in increasing rapidly. The subject of solar neutrinos has many seemingly independent aspects, both in its theoretical basis (involving nuclear, atomic, and particle physics, geochemistry, and astronomy). For many physicists, solar neutrinos constitute the low-energy frontier of high-energy physics. Results from all these disciplines are combined here, providing a timely and unified discussion of the field. Each chapter begins with a succinct overview of material to be presented and ends with an annotated bibliography. For advanced undergraduate students, but will be essential reading for all researchers interested in the physics of neutrinos and what they reveal about the nature of the Universe.
Download or read book Double Chooz and Reactor Neutrino Oscillation written by Thiago Junqueira de Castro Bezerra and published by Springer. This book was released on 2015-01-27 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is based on the author’s work at the Double Chooz Experiment, from 2010 to 2013, the goal of which was to search for electronic anti-neutrino disappearance close to nuclear power plant facilities as a result of neutrino oscillation. Starting with a brief review of neutrino oscillation and the most important past experimental findings in this field, the author subsequently provides a full and detailed description of a neutrino detector, from simulation aspects to detection principles, as well as the data analysis procedure used to extract the oscillation parameters. The main results in this book are 1) an improvement on the mixing angle, θ13, uncertainty by combining two data-sets from neutrino event selection: neutron capture on gadolinium and on hydrogen; and 2) the first measurement of the effective squared mass difference by combining the current reactor neutrino experimental data from Daya Bay, Double Chooz and RENO and taking advantage of their different reactor-to-detector distances. The author explains how these methods of combining data can be used to estimate these two values. Each method results in the best possible sensitivity for the oscillation parameters with regard to reactor neutrinos. They can be used as a standard method on the latest data releases from the current experiments.
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 Neutrinos in High Energy and Astroparticle Physics written by Jose Wagner Furtado Valle and published by John Wiley & Sons. This book was released on 2015-02-02 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: This self-contained modern textbook provides a modern description of the Standard Model and its main extensions from the perspective of neutrino physics. In particular it includes a thorough discussion of the varieties of seesaw mechanism, with or without supersymmetry. It also discusses schemes where neutrino mass arises from lighter messengers, which might lie within reach of the world's largest particle accelerator, the Large Hadron Collider. Throughout the text, the book stresses the role of neutrinos due to the fact that neutrino properties may serve as a guide to the correct model of unification, hence for a deeper understanding of high energy physics, and because neutrinos play an important role in astroparticle physics and cosmology. Each chapter includes summaries and set of problems, as well as further reading.
Download or read book Measurement of the Antineutrino Double Differential Charged Current Quasi Elastic Scattering Cross Section at MINERvA written by Cheryl E. Patrick and published by Springer. This book was released on 2017-11-15 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis represents the first double differential measurement of quasi-elastic anti-neutrino scattering in the few GeV range--a region of substantial theoretical and experimental interest as it is the kinematic region where studies of charge-parity (CP) violation in the neutrino sector most require precise understanding of the differences between anti-neutrino and neutrino scatter. This dissertation also presents total antineutrino-scintillator quasi-elastic cross sections as a function of energy, which is then compared to measurements from previous experiments. Next-generation neutrino oscillation experiments, such as DUNE and Hyper-Kamiokande, hope to measure CP violation in the lepton sector. In order to do this, they must dramatically reduce their current levels of uncertainty, particularly those due to neutrino-nucleus interaction models. As CP violation is a measure of the difference between the oscillation properties of neutrinos and antineutrinos, data about how the less-studied antineutrinos interact is especially valuable. The measurement described herewith determines the nuclear and instrumental effects that must be understood to undertake precision neutrino physics. As well as being useful to help reduce oscillation experiments' uncertainty, this data can also be used to study the prevalence of various correlation and final-state interaction effects within the nucleus. In addition to being a substantial scientific advance, this thesis also serves as an outstanding introduction to the field of experimental neutrino physics for future students.
Download or read book Observation of e Oscillation in the T2K Experiment written by Kei Ieki and published by Springer. This book was released on 2015-12-24 with total page 205 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this thesis the author contributes to the analysis of neutrino beam data collected between 2010 and 2013 to identify νμ→νe events at the Super-Kamiokande detector. In particular, the author improves the pion–nucleus interaction uncertainty, which is one of the dominant systematic error sources in T2K neutrino oscillation measurement. In the thesis, the measurement of νμ→νe oscillation in the T2K (Tokai to Kamioka) experiment is presented and a new constraint on δCP is obtained. This measurement and the analysis establish, at greater than 5σ significance, the observation of νμ→νe oscillation for the first time in the world. Combining the T2K νμ→νe oscillation measurement with the latest findings on oscillation parameters including the world average value of θ13 from reactor experiments, the constraint on the value of δCP at the 90% confidence level is obtained. This constraint on δCP is an important step towards the discovery of CP violation in the lepton sector.

This book was released on 2021-03-17 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: A mixture of memoir and biography, Chasing the Ghost: Nobelist Fred Reines and the Neutrino tells a deeply human story that appeals both to scientists and non-scientists. Although the book relates to the important discovery of neutrinos, it is more intimately about Fred Reines than the technical details of neutrino physics. Narrated in a fashion to interest and excite the reader, the science presented here is accessible to a broad audience. Coursing through Reines' life, his various challenges and encounters, the book reveals constants of his persona. Reines displayed a sustained consistency as a respected leader, admired by students and colleagues as a fount of big ideas and ambition. A continuing source of inspiration and motivation to others, his most basic consistency was his passion for science. The quest for knowledge about the wondrous universe is a profoundly human endeavor. Fred Reines' life and his unremitting scientific curiosity are emblematic of that truth.'This book is a most welcome account about Frederick Reines and his great contributions to neutrino physics and astrophysics. The methods he designed in the 1950s to discover neutrinos in nuclear reactor experiments are still being used. His later work included the detection of atmospheric neutrinos which was a forerunner to the discovery of neutrino oscillations, the ability of neutrinos to change from one type to another. This finding was a significant step to other experiments that aim to answer profound questions about the nature of the universe including why it is composed of matter.'Takaaki KajitaNobel Laureate in PhysicsNeutrino Researcher, University of Tokyo 'Cole has provided a compelling personal and scientific account of a remarkable pioneer in Neutrino Physics.'Arthur B McDonaldNobel Laureate in PhysicsDirector of the Sudbury Neutrino ObservatoryProfessor, Queen's University, Ontario, Canada
