Sterile-active neutrino oscillations and shortcuts in the extra dimension
Abstract
We discuss a possible new resonance in active-sterile neutrino oscillations arising in theories with large extra dimensions. Fluctuations in the brane effectively increase the path-length of active neutrinos relative to the path-length of sterile neutrinos through the extra-dimensional bulk. Well below the resonance, the standard oscillation formulas apply. Well above the resonance, active-sterile oscillations are suppressed. We show that a resonance energy in the range of 30-400 MeV allows an explanation of all neutrino oscillation data, including LSND data, in a consistent four-neutrino model. A high resonance energy implies an enhanced signal in MiniBooNE. A low resonance energy implies a distorted energy spectrum in LSND, and an enhanced {nu}{sub {mu}} depletion from a stopped-pion source. The numerical value of the resonance energy may be related back to the geometric aspects of the brane world. Some astrophysical and cosmological consequences of the brane-bulk resonance are briefly sketched.

In extra-dimensional scenarios oscillations between active and sterile neutrinos can be governed by a new resonance in the oscillation amplitude. This resonance results when cancellation occurs between two phase differences, the usual kinematic one coming from the neutrino mass-squared difference, and a geometric one coming from the difference in travel times of the sterile neutrino through the bulk relative to the active neutrino confined to the brane. In this work we introduce a specific metric for the brane-bulk system, from which we explicitly derive extra-dimensional geodesics for the sterile neutrino, and ultimately the oscillation probability of the active-sterile two-state system.more »

Measuring active-sterile neutrino oscillations with a stopped pion neutrino source
The possible existence of light sterile neutrinos is of great interest in many areas of particle physics, astrophysics, and cosmology. Furthermore, should the MiniBooNE experiment at Fermilab confirm the Liquid Scintillating Neutrino Detector (LSND) oscillation signal, then new measurements are required to identify the mechanism responsible for these oscillations. Possibilities include sterile neutrinos, CP or CPT violation, variable mass neutrinos, Lorentz violation, and extra dimensions. In this paper, we consider an experiment at a stopped pion neutrino source to determine if active-sterile neutrino oscillations with {delta}m{sup 2} greater than 0.1 eV{sup 2} can account for the signal. By exploiting stoppedmore » -
Fission cycling in supernova nucleosynthesis: Active-sterile neutrino oscillations
We investigate nucleosynthesis in the supernova post-core bounce neutrino-driven wind environment in the presence of active-sterile neutrino transformation. We consider active-sterile neutrino oscillations for a range of mixing parameters: vacuum mass-squared differences of 0.1 eV{sup 2}{<=}{delta}m{sup 2}{<=}100 eV{sup 2}, and vacuum mixing angles of sin{sup 2}2{theta}{sub v}{>=}10{sup -4}. We find a consistent r-process pattern for a large range of mixing parameters that is in rough agreement with the halo star CS 22892-052 abundances and the pattern shape is determined by fission cycling. We find that the allowed region for the formation of the r-process peaks overlaps the liquid scintillator neutronmore » -
Probing active to sterile neutrino oscillations in the LENS detector
Sterile neutrino ({nu}{sub s}) conversion in meter scale baselines can be sensitively probed using monoenergetic, sub-MeV, flavor-pure {nu}{sub e}'s from an artificial Megacurie source and the unique technology of the LENS low energy solar {nu}{sub e} detector. Active-sterile oscillations can be directly observed in the granular LENS detector itself to critically test and extend results of short baseline accelerator and reactor experiments.
