Book excerpt: Neutrinos are one of the most abundant particles in the universe. Because they have very little interaction with matter, however, they are incredibly difficult to detect. Neutrinos are similar to the more familiar electron, with one crucial difference: neutrinos do not carry electric charge. Because neutrinos are electrically neutral, they are not affected by the electromagnetic forces which act on electrons. Three types of neutrinos are known. Each type or 'flavour' of neutrino is related to a charged particle (which gives the corresponding neutrino its name). Hence, the 'electron neutrino' is associated with the electron, and two other neutrinos are associated with heavier versions of the electron called the muon and the tau. The book presents citations from the literature for the last three years from the journal literature and the existent book literature. Access is provided by subject, author and title indexes.

Book Synopsis A Search for Muon Neutrino to Electron Neutrino Oscillations in the MINOS Experiment by : Juan Pedro Ochoa-Ricoux
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.

Book Synopsis Measurement of Neutrino Interactions and Three Flavor Neutrino Oscillations in the T2K Experiment by : Tatsuya Kikawa
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.

Book Synopsis A Measurement of Muon Neutrino Disappearance with the MINOS Detectors and NuMI Beam by : Rustem Ospanov
Download or read book A Measurement of Muon Neutrino Disappearance with the MINOS Detectors and NuMI Beam written by Rustem Ospanov and published by . This book was released on 2008 with total page 560 pages. Available in PDF, EPUB and Kindle. Book excerpt: MINOS is a long-baseline two-detector neutrino oscillation experiment that uses a high intensity muon neutrino beam to investigate the phenomena of neutrino oscillations. The neutrino beam is produced by the NuMI facility at Fermilab, Batavia, Illinois, and is observed at near and far detectors placed 734 km apart. The neutrino interactions in the near detector are used to measure the initial muon neutrino flux. The vast majority of neutrinos travel through the near detector and Earth matter without interactions. A fraction of muon neutrinos oscillate into other flavors resulting in the disappearance of muon neutrinos at the far detector. This thesis presents a measurement of the muon neutrino oscillation parameters in the framework of the two-neutrino oscillation hypothesis.
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 The Search for High Energy Tau Neutrinos Using the IceCube Neutrino Observatory by : Logan James Wille
Download or read book The Search for High Energy Tau Neutrinos Using the IceCube Neutrino Observatory written by Logan James Wille and published by . This book was released on 2019 with total page 73 pages. Available in PDF, EPUB and Kindle. Book excerpt: High energy neutrinos provide a new frontier of astrophysical and particle physics research. Astrophysical neutrinos are produced at the same sources as hadronic cosmic rays throughout the universe in many different accelerators. These neutrinos propagate a very long distance to reach the Earth during which they experience oscillations between the flavors, including tau neutrinos which are not produced at the source. Astrophysical tau neutrinos are a clear sign of neutrino oscillations, which can shed light on beyond standard model physics at energy scales and distance scales not yet explored. The signature of the BSM physics can be seen in the flavor ratio of astrophysical neutrinos. However, astrophysical tau neutrinos have not yet been observed by IceCube, this dissertation is on my work to observe astrophysical tau neutrinos. The work presented here is about an improved analysis to observe astrophysical tau neutrinos using novel observation techniques, a critical key in measuring the astrophysical neutrino flavor ratio. Neutrino oscillations, interactions, and observe techniques will be explored along with the methods to improve a previous analysis of IceCube data to observe neutrinos. The main signature used to observe tau neutrinos is a double pulse waveform, where a single DOM observes the Cherenkov light signals associated with both the tau neutrino interaction and the decay of the tau that it produced. This analysis focuses on observing O (100 TeV) tau neutrinos via double pulse waveforms in 8.5 years of data. The analysis observed two neutrino candidates and one probable muon background event which resulting in setting upper limits of tau neutrino flux at 1.1×10^(−18) ×E^(−2.19), 2.5×10^(−18) ×E^(−2.5), and 6.0^(−18) ×E^(−2.9)GeV^(−1)cm^(−2)s^(−1)sr^(−1).

This book was released on 2017-09-13 with total page 180 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.

Book Synopsis New Initiatives On Lepton Flavor Violation And Neutrino Oscillation With High Intense Muon And Neutrino Sources by : Yoshitaka Kuno
Download or read book New Initiatives On Lepton Flavor Violation And Neutrino Oscillation With High Intense Muon And Neutrino Sources written by Yoshitaka Kuno and published by World Scientific. This book was released on 2002-10-07 with total page 262 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.
Book Synopsis Background Processes in the Electrostatic Spectrometers of the KATRIN Experiment by : Susanne Mertens
Download or read book Background Processes in the Electrostatic Spectrometers of the KATRIN Experiment written by Susanne Mertens and published by Springer Science & Business Media. This book was released on 2013-11-05 with total page 203 pages. Available in PDF, EPUB and Kindle. Book excerpt: Neutrinos continue to be the most mysterious and, arguably, the most fascinating particles of the Standard Model as their intrinsic properties such as absolute mass scale and CP properties are unknown. The open question of the absolute neutrino mass scale will be addressed with unprecedented accuracy by the Karlsruhe Tritium Neutrino (KATRIN) experiment, currently under construction. This thesis focusses on the spectrometer part of KATRIN and background processes therein. Various background sources such as small Penning traps, as well as nuclear decays from single radon atoms are fully characterized here for the first time. Most importantly, however, it was possible to reduce the background in the spectrometer by more than five orders of magnitude by eliminating Penning traps and by developing a completely new background reduction method by stochastically heating trapped electrons using electron cyclotron resonance (ECR). The work beautifully demonstrates that the obstacles and challenges in measuring the absolute mass scale of neutrinos can be met successfully if novel experimental tools (ECR) and novel computing methods (KASSIOPEIA) are combined to allow almost background-free tritium ß-spectroscopy.

Download or read book Muon Neutrino Disappearance in NOvA with a Deep Convolutional Neural Network Classifier written by and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The NuMI Off-axis Neutrino Appearance Experiment (NOvA) is designed to study neutrino oscillation in the NuMI (Neutrinos at the Main Injector) beam. NOvA observes neutrino oscillation using two detectors separated by a baseline of 810 km; a 14 kt Far Detector in Ash River, MN and a functionally identical 0.3 kt Near Detector at Fermilab. The experiment aims to provide new measurements of [Delta]m2 and [theta]23 and has potential to determine the neutrino mass hierarchy as well as observe CP violation in the neutrino sector. Essential to these analyses is the classification of neutrino interaction events in NOvA detectors. Raw detector output from NOvA is interpretable as a pair of images which provide orthogonal views of particle interactions. A recent advance in the field of computer vision is the advent of convolutional neural networks, which have delivered top results in the latest image recognition contests. This work presents an approach novel to particle physics analysis in which a convolutional neural network is used for classification of particle interactions. The approach has been demonstrated to improve the signal efficiency and purity of the event selection, and thus physics sensitivity. Early NOvA data has been analyzed (2.74×1020 POT, 14 kt equivalent) to provide new best- fit measurements of sin2([theta]23) = 0.43 (with a statistically-degenerate compliment near 0.60) and.
