Описание: This thesis describes the experimental work that finally led to a successful measurement of coherent elastic neutrino-nucleus scattering—a process proposed forty-three years ago. The experiment was performed at the Spallation Neutron Source facility, sited at Oak Ridge National Laboratory, in Tennessee.Of all known particles, neutrinos distinguish themselves for being the hardest to detect, typically requiring large multi-ton devices for the job. The process measured here involves the difficult detection of very weak signals arising from nuclear recoils (tiny neutrino-induced “kicks” to atomic nuclei), but leads to a much larger probability of neutrino interaction when compared to all other known mechanisms. As a result of this, “neutrino technologies” using miniaturized detectors (the author's was handheld and weighed only 14 kg) become a possibility. A large community of researchers plans to continue studying this process, facilitating an exploration of fundamental neutrino properties that is presently beyond the sensitivity of other methods.
Описание: Since The Discovery Of Neutrino Oscillations Neutrino Physics Has Become An Interesting Field Of Research In Physics. They Imply That Neutrino Must Have A Small Mass And That The Neutrinos, Coupled To The Charged Leptons, Are Mixtures Of The Mass Eigenstates, Analogous To The Flavor Mixing Of The Quarks. The Mixing Angles For The Quarks Are Small, But For The Leptons Two Of The Mixing Angles Are Large. The Masses Of The Three Neutrinos Must Be Very Small, Less Than 1 Ev, But From The Oscillation Experiments We Only Know The Mass Differences — The Absolute Masses Are Still Unknown. Also We Do Not Know, If The Masses Of The Neutrinos Are Dirac Masses, As The Masses Of The Charged Leptons And Of The Quarks, Or Whether They Are Majorana Masses.In This Volume, An Overview Of The Present State Of Research In Neutrino Physics Is Given By Well-Known Experimentalists And Theorists. The Contents — Originated From Talks And Discussions At A Recent Conference Addressing Some Of The Most Pressing Open Questions In Neutrino Physics — Range From The Oscillation Experiments To Cp-Violation For Leptons, To Texture Zero Mass Matrices And To The Role Of Neutrinos In Astrophysics And Cosmology.
Описание: This thesis details significant improvements in the understanding of the nuclear EMC effect and nuclear shadowing in neutrino physics, and makes substantial comparisons with electron scattering physics. Specifically, it includes the first systematic study of the EMC ratios of carbon, iron and lead to plastic scintillator of neutrinos. The analysis presented provides the best evidence to date that the EMC effect is similar between electrons and neutrinos within the sensitivity of the data. Nuclear shadowing is measured systematically for the first time with neutrinos. In contrast with the data on the EMC effect, the data on nuclear shadowing support the conclusion that nuclear shadowing may be stronger for neutrinos than it is for electrons. This conclusion points to interesting new nuclear physics.
Описание: This book presents a major step forward in experimentally understanding the behavior of muon neutrinos and antineutrinos. 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.

Описание: As the main scientific analysis, a search for high-energy neutrino emission from the region of the Fermi bubbles has been performed using data from the ANTARES detector. The sensitivity improves as more data are accumulated (more than 65% gain in the sensitivity is expected once 2012-2016 data are added to the analysis).
