Next Discoveries In Neutrino Mixing: Electron Neutrino Appearance, Hongyue Duyang

Theses and Dissertations

The discovery of neutrino oscillation is a clear evidence of new physics beyond the Standard Model. Measurements of electron neutrino ($\nu_e$) and electron anti-neutrino $\bar{\nu}_{e}$ appearances are the most important channels to complete the neutrino mixing matrix. In a $ \nu_{e} $/$\bar{\nu}_{e}$ appearance experiment, a near detector (ND) is used to constrain the neutrino flux and measure the backgrounds to the signal. Backgrounds to the $ \nu_{e} $ appearance comes from Neutral Current Muon Neutrino Interactions ($\nu_{\mu}$-NC), Charged Current Muon Neutrino Interactions ($\nu_{\mu}$-CC), beam $ \nu_{e} $ events and outside backgrounds. The background components are then extrapolated to the far …
