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 …

Development of metal loaded liquid scintillators for future detectors to investigate neutrino properties
Several future neutrino experiments call for metal loaded liquid scintillators for neutrino detection. The challenge in the development of such scintillators is how to dissolve large amounts of the metal in an organic liquid scintillator without degrading the optical properties. A promising new …
