This book was released on 2017-09-13 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis reports the measurement of muon neutrino and antineutrino disappearance and electron neutrino and antineutrino appearance in a muon neutrino and antineutrino beam using the T2K experiment. It describes a result in neutrino physics that is a pioneering indication of charge-parity (CP) violation in neutrino oscillation; the first to be obtained from a single experiment. Neutrinos are some of the most abundant—but elusive—particles in the universe, and may provide a promising place to look for a potential solution to the puzzle of matter/antimatter imbalance in the observable universe. It has been firmly established that neutrinos can change flavour (or ‘oscillate’), as recognised by the 2015 Nobel Prize. The theory of neutrino oscillation allows for neutrinos and antineutrinos to oscillate differently (CP violation), and may provide insights into why our universe is matter-dominated. Bayesian statistical methods, including the Markov Chain Monte Carlo fitting technique, are used to simultaneously optimise several hundred systematic parameters describing detector, beam, and neutrino interaction uncertainties as well as the six oscillation parameters.

This book was released on 2020-09-14 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis reports the calculation of neutrino production for the T2K experiment; the most precise a priori estimate of neutrino production that has been achieved for any accelerator-based neutrino oscillation experiment to date. The production of intense neutrino beams at accelerator facilities requires exceptional understanding of chains of particle interactions initiated within extended targets. In this thesis, the calculation of neutrino production for T2K has been improved by using measurements of particle production from a T2K replica target, taken by the NA61/SHINE experiment. This enabled the reduction of the neutrino production uncertainty to the level of 5%, which will have a significant impact on neutrino oscillation and interaction measurements by T2K in the coming years. In addition to presenting the revised flux calculation methodology in an accessible format, this thesis also reports a joint T2K measurement of muon neutrino and antineutrino disappearance, and the accompanying electron neutrino and antineutrino appearance, with the updated beam constraint.

This book was released on 2018-03-22 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.

Download or read book Measurement of Pion Carbon Cross Sections at DUET and Measurement of Neutrino Oscillation Parameters at the T2K Experiment written by Elder Sebastian Pinzon Guerra and published by . This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Tokai-to-Kamioka (T2K) experiment is a long baseline neutrino oscillation experiment. An intense muon neutrino (or antineutrino) beam is produced at the Japan Proton Accelerator Research Complex (J-PARC) by protons hitting a graphite target. The neutrinos are measured 280 m from the target, and again 295 km across Japan using the Super-Kamiokande detector. This allows for the study of the neutrino oscillations in four channels: the electron neutrino and antineutrino appearance, and muon neutrino and antineutrino disappearance. In T2K, neutrinos are observed primarily via charged current quasi-elastic scattering (CCQE) interactions, as well as charged current single pion (CC1) production. The pion is free to interact inside and outside the nucleus primarily via absorption and charge exchange processes. Reducing the uncertainties on these cross sections reduces the systematic uncertainties for neutrino oscillation measurements. The Dual Use Experiment at TRIUMF (DUET) was conducted to address this issue. This thesis describes the recent results from DUET: the most precise measurements of absorption and charge exchange cross sections of pion on carbon for the momentum range of 201.6~295.1 MeV/c. These DUET measurements, along with existing pion-nucleus scattering data for different atomic nuclei, are used to improve the cascade model that simulates pion-nucleus scattering in T2K, and to reduce the associated systematic uncertainties. These improvements are used in a Markov Chain Monte Carlo neutrino oscillation analysis of the T2K Run 1-8 data, corresponding to 14.7x10e20 protons-on-target in neutrino mode and 7.6x10e20 in antineutrino mode. As a result, the most precise measurement of the parameters that govern the neutrino oscillation phenomenon is obtained. In particular, the values indicative of no matter-antimatter asymmetry (CP-conservation) are excluded at the 95.4% (2-sigma) level. This constitutes the world-leading constraint for CP-violation in the leptonic sector.

Available in PDF, EPUB and Kindle. Book excerpt: The study of neutrinos and their interaction with matter has made many important contributions to our present knowledge of physics. This advanced text introduces neutrino physics and presents a theoretical framework for describing relativistic particles. It gives a pedagogical description of the neutrino, its properties, the standard model of electroweak interactions, and neutrino scattering from leptons and nucleons. Focusing on the role of nuclear effects, the discussion extends to various processes of quasielastic, inelastic, and deep inelastic scattering from nucleons and nuclei. Neutrino sources, detection and oscillation, along with the role of neutrinos in astrophysics and motivation for the need of physics beyond the standard model are discussed in detail. This topical book will stimulate new ideas and avenues for research, and will form a valuable resource for advanced students and researchers working in the field of neutrino physics.
Download or read book Measurement of Neutrino Interactions and Three Flavor Neutrino Oscillations in the T2K Experiment written by Tatsuya Kikawa and published by Springer. This book was released on 2015-09-18 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is based on the author's work in the T2K long-baseline neutrino oscillation experiment, in which neutrinos are generated by a proton beam and are detected by near and far neutrino detectors. In order to achieve the precise measurement of the neutrino oscillation, an accurate understanding of the neutrino beam and the neutrino interaction is essential. Thus, the author measured the neutrino beam properties and the neutrino interaction cross sections using a near neutrino detector called INGRID and promoted a better understanding of them. Then, the author performed a neutrino oscillation analysis using the neutrino beam and neutrino interaction models verified by the INGRID measurements. As a result, some values of the neutrino CP phase are disfavored at the 90% confidence level. If the measurement precision is further improved, we may be able to discover the finite CP phase which involves the CP violation. Thus, this result is an important step towards the discovery of CP violation in the lepton sector, which may be the key to understanding the origin of the matter–antimatter asymmetry in the universe.

Available in PDF, EPUB and Kindle. Book excerpt: Small neutrino masses are the first signs of new physics beyond the Standard Model of particle physics. Since the first edition of this textbook appeared in 2010, the Nobel Prize has been awarded "for the discovery of neutrino oscillations, which shows that neutrinos have mass". The measurement of the small neutrino mixing angle $\theta_{13}$ in 2012, launched the precision stage of the investigation of neutrino oscillations. This measurement now allows such fundamental problems as the three-neutrino mass spectrum - is it normal or inverted? – and the $CP$ violation in the lepton sector to be tackled. In order to understand the origin of small neutrino masses, it remains crucial to reveal the nature of neutrinos with definite masses: are they Dirac neutrinos possessing a conserved lepton number, which distinguishes neutrinos and antineutrinos, or are they Majorana neutrinos with identical neutrinos and antineutrinos? Experiments searching for the neutrinoless double beta decay are presently under way to answer this fundamental question. The second edition of this book comprehensively discusses all these important recent developments. Based on numerous lectures given by the author, a pioneer of modern neutrino physics (recipient of the Bruno Pontecorvo Prize 2002), at different institutions and schools, it offers a gentle yet detailed introduction to the physics of massive and mixed neutrinos that prepares graduate students and young researchers entering the field for the exciting years ahead in neutrino physics.

We now know that neutrinos have nonzero, small masses. In numerous exp- iments with solar, atmospheric, reactor and accelerator neutrinos a new p- nomenon, neutrino oscillations, was observed.

The discovery of neutrino oscillations opened a new era in neutrino physics: an era of investigation of neutrino masses, mixing, magnetic moments and other neutrino properties. After the establishment of the Standard Model of the el- troweak interaction at the end of the seventies, the discovery of neutrino masses was the most important discovery in particle physics. Small neutrino masses cannot be explained by the standard Higgs mechanism of mass generation. For their explanation a new mechanism is needed. Thus, small neutrino masses is the ?rst signature in particle physics of a new beyond the Standard Model physics. It took many years of heroic efforts by many physicists to discover n- trino oscillations.

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.

This book was released on 2010 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: Elucidating the nature of neutrino oscillation continues to be a goal in the vanguard of the efforts of physics experiment. As neutrino oscillation searches seek an increasingly elusive signal, a thorough understanding of the possible backgrounds becomes ever more important. Measurements of neutrino-nucleus interaction cross sections are key to this understanding. Searches for [nu]{sub {mu}} → [nu]{sub e} oscillation - a channel that may yield insight into the vanishingly small mixing parameter [theta]13, CP violation, and the neutrino mass hierarchy - are particularly susceptible to contamination from neutral current single [pi]° (NC 1[pi]°) production. Unfortunately, the available data concerning NC 1[pi]° production are limited in scope and statistics. Without satisfactory constraints, theoretical models of NC 1[pi]° production yield substantially differing predictions in the critical E{sub {nu}} ≈ 1 GeV regime. Additional investigation of this interaction can ameliorate the current deficiencies. The Mini Booster Neutrino Experiment (MiniBooNE) is a short-baseline neutrino oscillation search operating at the Fermi National Accelerator Laboratory (Fermilab). While the oscillation search is the principal charge of the MiniBooNE collaboration, the extensive data (≈ 106 neutrino events) offer a rich resource with which to conduct neutrino cross section measurements. This work concerns the measurement of both neutrino and antineutrino NC 1[pi]° production cross sections at MiniBooNE. The size of the event samples used in the analysis exceeds that of all other similar experiments combined by an order of magnitude. We present the first measurements of the absolute NC 1[pi]° cross section as well as the first differential cross sections in both neutrino and antineutrino mode. Specifically, we measure single differential cross sections with respect to pion momentum and pion angle. We find the flux-averaged, total cross sections for NC 1[pi]° production on CH2 to be (4.76 ± 0.05{sub stat} ± 0.76{sub sys}) x 10−4° cm2/nucleon at E{sub {nu}} = 808 MeV for neutrino induced production and (1.48 ± 0.05{sub stat} ± 0.23{sub sys}) x 10−4° cm2/nucleon at E{sub {nu}} = 664 MeV for antineutrino induced production.
