Simulating low-energy neutrino interactions with MARLEY

Neutrino - Photon Interactions at Low Energy

We discuss ν−γ interactions in the presence of a homogeneous magnetic field with energies less than pair production threshold. The neutrinos are taken to be massless with only standardmodel couplings. The magnetic field fulfills the dual purpose of inducing an effective neutrinophoton vertexes and of modifying the photon dispersion relation. Our conclusion is ν − γ interactions are too weak to ...

Low-energy neutrino-photon inelastic interactions

The computation of the polarized amplitudes and cross section of the processes γν → γγν, γγ → γνν̄ and νν̄ → γγγ is described. We used an effective lagrangian approach for energies below the threshold for e+e− pair production and the complete computation at higher energies for application in supernova dynamics. Leading contributions of physics beyond the SM are also commented.

Low-Energy Neutrino Physics and Neutrino Mass

Exploring Neutrino Mixing with Low Energy Superbeams

We explore as clearly as possible the features of neutrino oscillation which are relevant for measurements of the CP violating Kobayashi-Maskawa phase δ and the sign of ∆m213. We focus on the so called low-energy option and discuss principles for optimizing experimental parameters to measure these two quantities simultaneously. Toward the goal, we first formulate a method for obtaining a bird-e...

Low Energy Neutrino Factory Design

The design of a low energy (4 GeV) Neutrino Factory is described, along with its expected performance. The Neutrino Factory uses a high energy proton beam to produce charged pions. The  decay to produce muons (), which are collected, accelerated, and stored in a ring with long straight sections. Muons decaying in the straight sections produce neutrino beams. The scheme is based on previous de...
