 Title: Search For Muon-associated Neutrino---> Electron-associated Neutrino Oscillations In A Narrow Band Neutrino Beam Author(s): O'Brien, Edward John Department / Program: Physics Discipline: Physics Degree Granting Institution: University of Illinois at Urbana-Champaign Degree: Ph.D. Genre: Dissertation Subject(s): Physics, Elementary Particles and High Energy Abstract: An experiment that looked for the oscillation $\nu\sb\mu \Rightarrow \nu\sb{e}$ was performed using a narrow band $\nu\sb\mu$ beam produced by the AGS at Brookhaven National Lab. Both the $\nu\sb\mu$ and $\nu\sb{e}$ reactions in our detector are analyzed. The number of $\nu\sb{e}$ events found in the detector is compared to the expected background from Monte Carlo calculations and an excess of 22.4 $\pm$ 5.6 $\pm$ $\sbsp{3.8}{4.4}$ events above background is found. The excess represents a 3 standard deviation effect and may suggest a neutrino oscillation.The ratio of the acceptance corrected number of $\nu\sb{e}$ and $\nu\sb\mu$ events is calculated from the data. The value is ${\cal R}$ = ${\nu\sb{e}\over \nu\sb\mu}$ = 0.0184 $\pm$.0085.
