The NuFact ...

This book describes all aspects of neutrino physics, focusing on what is known and what we may hope to know about the mass of the neutrino and its particle-antiparticle symmetry, two of the most pressing questions in modern particle physics. The authors discuss neutrinos and their decisive role ...
Review of existing neutrino data shows that it cannot all be described with the two mass-squared differences and three mixing angles in simple mixing models. Mindful of the new neutrino interactions present in many particle physics models, we investigate these direct interactions and determine that they could affect the flavor-change ...
We discuss simplified models for photo-meson production in cosmic accelerators, such as active galactic nuclei (AGNs) and gamma-ray bursts (GRBs). Our self-consistent models are directly based on the underlying physics used in the SOPHIA software and can be easily adapted if new data are included. They allow for the efficient computation of ...

The MiniBooNE experiment at Fermilab was designed to test the LSND evidence for oscillations [1]. The first MiniBooNE oscillation result in neutrino mode [2] shows no significant excess of events at higher energies (Ev > 475 MeV), although a sizeable excess is observed at lower energies (Ev < 475 MeV). The lack of a significant excess at higher energies allows MiniBooNE ...

The energy spectrum and flux of neutrinos from a linear pion accelerator are calculated analytically under the assumption of a uniform accelerating gradient. The energy of a neutrino from this source reacting in a detector can be determined from timing and event position information.
Solar neutrino experiments were originally conceived as a way to demonstrate that nuclear reactions are responsible for energy generation in stars. When solar neutrinos were first detected the measured flux was much less than what solar models predicted. The Solar Neutrino Problem thus came to be and it persisted for over thirty years. ...
