Book Description
The last unknown neutrino mixing angle theta_13 is one of the fundamental parameters of nature; it is also a crucial parameter for determining the sensitivity of future long-baseline experiments aimed to study CP violation in the neutrino sector. Daya Bay is a reactor neutrino oscillation experiment designed to achieve a sensitivity on the value of sin^2(2*theta_13) to better than 0.01 at 90percent CL. The experiment consists of multiple identical detectors placed underground at different baselines to minimize systematic errors and suppress cosmogenic backgrounds. With the baseline design, the expected anti-neutrino signal at the far site is about 360 events per day and at each of the near sites is about 1500 events per day. An overview and current status of the experiment will be presented.

Book Description
Over the past 80 years, our understanding of neutrinos has gone from nothing to nothing, and many major breakthroughs have been made. The Daya Bay experiment is China's first attempt to study neutrino oscillation, and it is the beginning of China's entry into the basic scientific research of neutrinos. The book introduces to readers about what neutrinos are, what neutrino oscillations are, how the Daya Bay Experiment was designed, developed and built and how it works. The book also includes the meaning of The Daya Bay experiment and what important results it has achieved.

Book Description
This book reviews the status of a very exciting field OCo neutrino oscillations OCo at a very important time. The fact that neutrinos have mass has only been proved in the last few years and the acceptance of that fact has opened up a whole new area of study to understand the fundamental parameters of the mixing matrix. The book summarizes the results from all the experiments which have played a role in the measurement of neutrino oscillations and briefly describes the scope of some new planned experiments. Contributions include a theoretical introduction by Stephen Parke from FNAL, as well as articles from all the major experimental groups who have been pivotal in uncovering the nature of the neutrino mass. Sample Chapter(s). Chapter 1: Neutrino Oscillation Phenomenology (677 KB). Contents: Neutrino Oscillation Phenomenology (S J Parke); The Super-Kamiokande Experiment (C W Walter); Sudbury Neutrino Observatory (S J M Peeters & J R Wilson); Neutrino Oscillation Physics with KamLAND: Reactor Antineutrinos and Beyond (K M Heeger); K2K: KEK to Kamioka Long-Baseline Neutrino Oscillation Experiment (R J Wilkes); MINOS (P Vahle); The LSND and KARMEN Neutrino Oscillation Experiments (W C Louis); MiniBooNE (S J Brice); The OPERA Experiment in the CNGS Beam (D Autiero et al.); The T2K Experiment (D L Wark); The NO?A Experiment (G J Feldman); Double Chooz (G A Horton-Smith & T Lasserre); Daya Bay: A Sensitive Determination of ? 13 with Reactor Antineutrinos (K B Luk & Y Wang).

Book Description
Neutrino oscillation is the quantum mechanical phenomenon whereby neutrinos or antineutrinos can spontaneously transform from one of three flavors0́4 electron, muon, or tau0́4 to another. The Daya Bay Reactor Neutrino Experiment has measured neutrino mixing angle Ø13, for the first time, to world-leading precision. The analysis in this dissertation reports sin22Ø13 = 0.088 0.0088, m232 = 2.54+0:172:54+0:17-0.18 *108́ eV2 and m231 = 2.62 108́23 eV2, assuming m221 = 7.50*108-5 eV2 and normal hierarchy. These measurements were accomplished by the early deployment of six functionally identical detectors to observe antineutrino flux from six nuclear reactors, between 2 to 12 MeV. Half the detectors are sited near the position of maximal oscillation, about 1600m from the reactors, while the rest are located 500m and 550m away at two sites, where the oscillation probability is low. The relative comparison of antineutrino rates and energies at identical near and far detectors provides a direct measurement of Ø13 and m2, while greatly reducing systematic uncertainties. The chapters that follow explain neutrino oscillations, and experiment strategy and construction. My contributions to the experiment are highlighted in more detail in the introductions to chapters 3 through 9. These include a detector camera monitoring system, a sensitivity calculation that helped motivate the early six-detector analysis, and the measurements of oscillation parameters from antineutrino rates and spectra.

Book Description
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.

Book Description
Our Universe is made of a dozen fundamental building blocks. Among these, neutrinos are the most mysterious - but they are the second most abundant particles in the Universe. This book provides detailed discussions of how to describe neutrinos, their basic properties, and the roles they play in nature.
