Title: An Analysis of Muon Neutrino Disappearance from the NuMI Beam Using an Optimal Track Fitter

The NOvA experiment is a long-baseline neutrino oscillation experiment based out of Fermilab National Accelerator Laboratory that uses two liquid scintillator detectors, one at Fermilab (the \near" detector) and a second 14 kton detector in northern Minnesota (the \far" detector.) The primary physics goals of the NOvA experiment are to measure neutrino mixing parameters through both the vμ disappearance and ve appearance channels using neutrinos from the newly upgraded NuMI beam line. The NOvA vμ disappearance analysis can significantly improve the world's best measurement of sin2 θ 23. This analysis proceeds by using the measured vμ charged-current energy spectrum in the near detector to predict the spectrum in the far detector, and comparing this to the measured spectrum to obtain a best fit for the oscillation parameters sin2 θ 23 and Δm2 32. Since this fit is governed by the shape of the energy spectrum, the best fit will be maximized by obtaining the best possible energy resolution for the individual neutrino events. This dissertation describes an alternate vμ disappearance analysis technique for the NOvA experiment, based on the idea that estimating the energy resolution of the individual events will allow them to be separated into different energy resolution samplesmore » in order to improve the final fit.« less
