Book excerpt: This thesis presents measurements of the oscillations of muon antineutrinos in the atmospheric sector, where world knowledge of antineutrino oscillations lags well behind the knowledge of neutrinos, as well as a search for v? → $ar{v}$? transitions. Differences between neutrino and antineutrino oscillations could be a sign of physics beyond the Standard Model, including non-standard matter interactions or the violation of CPT symmetry. These measurements leverage the sign-selecting capabilities of the magnetized steel-scintillator MINOS detectors to analyze antineutrinos from the NuMI beam, both when it is in neutrino-mode and when it is in antineutrino-mode. Antineutrino oscillations are observed at.

Download or read book Study of Antineutrino Oscillations Using Accelerator and Atmospheric Data in MINOS written by Son Van Cao and published by . This book was released on 2014 with total page 560 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Main Injector Neutrino Oscillation Search (MINOS) is a long baseline experiment that was built for studying the neutrino oscillation phenomena. The MINOS experiment uses high intensity muon neutrino and antineutrino beams created by Neutrinos at the Main Injector facility (NuMI) at the Fermi National Accelerator Laboratory (Fermilab). Neutrino interactions are recorded by two sampling steel-scintillator tracking calorimeters: 0.98 kton Near Detector at Fermilab, IL and 5.4 kton Far Detector at the Soudan Underground Laboratory, MN. These two detectors are functionally identical, which helps to reduce the systematic uncertainties in the muon neutrino and antineutrino disappearance measurements. The Near Detector, located 1.04 km from the neutrino production target, is used to measure the initial beam composition and neutrino energy proximal to the neutrino source. The collected data at the Near Detector is then used to predict energy spectrum in the Far Detector. By comparing this prediction to collected data at the Far Detector, which is 735 km away from the target, it enables a measurement of a set of parameters that govern the neutrino oscillation phenomenon. The flexibility of the NuMI beam configuration and the magnetization of the MINOS detectors facilitate the identification of v[subscript mu] and v̄[subscript mu] charged-current interactions on an event-by-event basis. This enables one to measure neutrino and antineutrino oscillation parameters independently and therefore allows us to test the CPT symmetry in the lepton sector. To enhance the sensitivity of the oscillation parameters measurement, a number of techniques have been implemented. Event classification, shower energy estimation and energy resolution bin fitting, which are described in this dissertation, are three of these techniques. Moreover, the most stringent constraints on oscillation parameters can be achieved by combining multiple data sets. This dissertation reports the measurement of antineutrino oscillation parameters using the complete MINOS accelerator and atmospheric data set of charged-current v̄[subscript mu] events.

This book was released on 2018-03-23 with total page 580 pages. Available in PDF, EPUB and Kindle. Book excerpt: The neutrino is the most fascinating elementary particle due to its elusive nature and outstanding properties that have attracted the interest of generations of physicists since 1930, when it was first postulated by Wolfgang Pauli as a 'desperate remedy' to explain the apparent energy violation in the beta decay. Many fundamental discoveries in particle physics had the neutrino involved in one way or another. To date, neutrino physics is still one of the hottest topics of modern particle physics. Key experiments and significant theoretical developments have contributed in building up what we can call now the Standard Model of Neutrino Physics.The aim of the book is to provide graduate students and young researchers a comprehensive tutorial in modern neutrino physics, specially tailored with emphasis on the educational aspects. It provides an overview of the basics and of recent achievements in the field, from both experimental and theoretical points of view.

Available in PDF, EPUB and Kindle. Book excerpt: The physics of neutrinos--uncharged elementary particles that are key to helping us better understand the nature of our universe--is one of the most exciting frontiers of modern science. This book provides a comprehensive overview of neutrino physics today and explores promising new avenues of inquiry that could lead to future breakthroughs. The Physics of Neutrinos begins with a concise history of the field and a tutorial on the fundamental properties of neutrinos, and goes on to discuss how the three neutrino types interchange identities as they propagate from their sources to detectors. The book shows how studies of neutrinos produced by such phenomena as cosmic rays in the atmosphere and nuclear reactions in the solar interior provide striking evidence that neutrinos have mass, and it traces our astounding progress in deciphering the baffling experimental findings involving neutrinos. The discovery of neutrino mass offers the first indication of a new kind of physics that goes beyond the Standard Model of elementary particles, and this book considers the unanticipated patterns in the masses and mixings of neutrinos in the framework of proposed new theoretical models. The Physics of Neutrinos maps out the ambitious future facilities and experiments that will advance our knowledge of neutrinos, and explains why the way forward in solving the outstanding questions in neutrino science will require the collective efforts of particle physics, nuclear physics, astrophysics, and cosmology.

Available in PDF, EPUB and Kindle. Book excerpt: The discovery of neutrino oscillations, and hence neutrino mass, in both solar and atmospheric neutrinos has been one of the major recent advances in particle physics. Among the many experiments that contributed to the study of this phenomenon. Super-Kamiokande is regarded as the experiment having established neutrino oscillations using atmospheric neutrinos. The final data sample of 5.90 kiloton-year exposure collected by the Soudan 2 detector is studied for the effects of atmospheric neutrino oscillations. These data are analyzed with a maximum likelihood analysis of the neutrino L/ E distribution using the Feldman-Cousins approach. The result confirms the discovery of oscillations in atmospheric neutrinos.

Available in PDF, EPUB and Kindle. Book excerpt: Underground proton decay detectors record a sizeable number of atmospheric neutrino-induced events. These neutrinos come primarily from the decay of pions and muons produced in cosmic ray showers in the earth's atmosphere. The expected flux ratio of muon neutrinos to electron neutrinos traversing an underground detector,??/?{sub e}, is about 2. The combined effects of detector systematics and nuclear cross section differences between?{sub mu} and?{sub e} interactions typically reduce the measured?{sub mu}/?3 event ratio to about 1. Over the last decade, both the Kamioka detector in Japan and the IMB detector in the United States have made high-statistics measurements of the atmospheric neutrino event ratio. Both groups have presented strong experimental evidence that the underground?{sub mu}/?{sub e} event ratio is substantially smaller than predicted. In both cases, a statistically significant deficit of muon neutrino-induced events is measured. One possible explanation of the muon neutrino deficit is that these neutrinos are undergoing flavor oscillations between their production points in the atmosphere and their interaction points in underground detectors. An MSW effect interpretation of solar neutrino experiments implies a?{sub e} →?{sub mu} oscillation region in?m2-sin2(2?) space at least two orders of magnitude lower in?m2 than the best fit point of the Kamioka result. It is therefore usually assumed that the relevant flavor oscillation for atmospheric muon neutrinos would be?{sub mu} →?{sub r}. The Soudan 2 nucleon decay detector is now approaching completion and collecting data. It will be able to make low-background measurements of atmospheric neutrinos in the next few years to check the possibility that atmospheric neutrinos undergo detectable flavor oscillations.

This book was released on 2002 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: The area of physics involving muons and neutrinos has become exciting in particle physics. Using their high intensity sources, physicists undertake, in various ways, extensive searches for new physics beyond the Standard Model, such as tests of supersymmetric grand unification (SUSY-GUT) and precision measurements of the muon and neutrino properties, which will in future extend to ambitious studies such as determination of the three-generation neutrino mixing matrix elements and CP violation in the lepton sector. The physics of this field is advancing, with potential improvements of the sources. Many R&D projects, such as those concerning high intensity, low energy muon sources or a neutrino factory, are being carried out or planned at various places. Some of those topics are included in this book. Contents: Muon Applied Science: Status at the End of the 20th Century (K Nagamine); Lepton Flavor Violation and Supersymmetric Models with Right-Handed Neutrino (D Nomura); Neutrino Oscillation Scenarios and GUT Model Predictions (C Albright); The MECO Experiment (J Sculli); CP Violation and Atmospheric Neutrinos (I Stancu et al.); Neutrino Oscillations with Four Generations (O Yasuda); Ambiguities of Theoretical Parameters and CP/T Violation in Neutrino Factories (M Koike et al.); Testing Neutrino Properties at Long Baseline Experiments and Neutrino Factories (S Pakvasa); Next Generation Water Cherenkov Detector at Kamioka (K Nakamura); and other papers.

This book was released on 2007 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: The third category of non-standard theory involves vanishing neutrinos caused by neutrino decoherence and neutrino decay. Our study shows that it is unlikely to explain SK atmospheric neutrino zenith angle distributions using these two non-oscillatory models. By treating them as sub-dominant effects, limits on these two types of new physics are set based on several specific models.
