Neutrino Oscillations: Eighty Years In Review
<p>In order to discuss neutrino oscillations, it is necessary to have knowledge of the developments in the field spanning the last eighty years. The existence of the neutrino was posited by Wolfgang Pauli in 1930 to account for the mass defect in beta decay, and to this day physicists are still …

Measuring theta?? via muon neutrino to electron neutrino oscillations in the MINOS experiment
One of the primary goals in neutrino physics at the present moment is to make a measurement of the neutrino oscillation parameter B13 . This parameter, in addition to being unknown, could potentially allow for the introduction of CP violation into the lepton sector. The MINOS long-baseline neutrino …

Looking for matter enhanced neutrino oscillations via day v. night asymmetries in the NCD phase of the Sudbury Neutrino Observatory
To measure the regeneration of electron neutrinos during passage through the Earth via the MSW effect, the difference in electron neutrino flux between day and night is measured at the Sudbury Neutrino Observatory (SNO). To be able to distinguish an actual discrepancy from an artifact, the detector …
