A Search for Muon Neutrino to Electron Neutrino Oscillations by Juan Pedro Ochoa-Ricoux

By Juan Pedro Ochoa-Ricoux

A look for Muon Neutrino to Electron Neutrino Oscillations within the MINOS Experiment is a tour de force that summarizes, basically and in a few intensity, a lot of Ochoa’s enormous physique of labor which has had an incredible impression on MINOS. the center piece of the thesis is the hunt for muon neutrino to electron neutrino oscillations, which might point out a non-zero blending perspective among the 1st and 3rd neutrino generations (θ13), at the moment the “holy grail” of neutrino physics. The optimum extraction of the electron neutrino oscillation sign relies at the novel “library occasion matching” (LEM) technique which Ochoa built and applied including colleagues at Caltech and at Cambridge, which improves MINOS’ succeed in for constructing an oscillation sign over the other technique. LEM will now be the root for MINOS’ outcome, and may most likely preserve MINOS on the leading edge of this box until eventually it completes its facts taking in 2011. Ochoa and his colleagues additionally constructed the winning plan to run MINOS with a beam tuned for antineutrinos, to make a delicate attempt of CPT symmetry by means of evaluating the inter-generational mass splitting for neutrinos and antineutrinos. Ochoa’s in-depth, inventive method of the answer of a number of complicated experimental difficulties is a phenomenal instance for graduate scholars and longtime practitioners of experimental physics alike. probably the most interesting leads to this box to emerge within the close to destiny could locate their foundations during this thesis, for which Ochoa used to be provided the nationwide Prize for adolescence of Mexico in 2009.

This Doctoral Thesis has been accredited via California Institute of know-how, Pasadena, USA.

Random Matrices, Random Processes and Integrable Systems

This ebook explores the awesome connections among domain names that, a priori, appear unrelated: Random matrices (together with linked random methods) and integrable structures. The kinfolk among random matrix types and the idea of classical integrable platforms have lengthy been studied. those seem generally within the deformation thought, while parameters characterizing the measures or the area of localization of the eigenvalues are different.

Ml þ n þ p: ð2:37Þ In this case the neutron was detected through its capture by a deuteron to form a tritium nucleus, a process that results in the emission of a gamma ray of roughly 6 MeV. Third, a neutrino of any flavor could also interact through electron elastic scattering (ES) reaction, ml þ eÀ ! ml þ eÀ ; ð2:38Þ where the neutrino imparts some of its energy to an atomic electron. The NC and ES reactions are sensitive to all neutrino flavors, while the CC reaction is only sensitive to electron neutrinos.
