The Short-Baseline Neutrino Program at Fermilab

Short-Baseline Neutrino Oscillations at a Neutrino Factory

Within the framework of three-neutrino and four-neutrino scenarios that can describe the results of the LSND experiment, we consider the capabilities of short baseline neutrino oscillation experiments at a neutrino factory. We find that, when short baseline (L ∼ 100 km) neutrino factory measurements are used together with other accelerator-based oscillation results, the complete three-neutrino ...

Short-Baseline Electron Neutrino Disappearance at a Neutrino Factory

We discuss short-baseline and very-short-baseline νe and ν̄e disappearance at a neutrino factory. We take into account geometric effects, such as from averaging over the decay straights, and the uncertainties of the cross sections. We follow an approach similar to reactor experiments with two detectors: we use two sets of near detectors at different distances to cancel systematics. We demonstrat...

Neutrino Oscillation Experiments at Fermilab

Neutrinos are special. They are the only elementary fermions which are neutral, thus they can be their own antiparticles. Their masses (if nonzero) are several orders of magnitude smaller than those of charged leptons or quarks. These two facts may be, in fact, related: with both Dirac and Majorana, masses present, the neutrino mass eigenstates will naturally split, with the light mass eigensta...

Long Baseline Neutrino Physics: From Fermilab to Kamioka

We have investigated the physics potential of very long baseline experiments designed to measure νμ → νe oscillation probabilities. The principles of our design are to tune the beam spectrum to the resonance energy for the matter effect, and to have the spectrum cut off rapidly above this energy. The matter effect amplifies the signal, and the cut-off suppresses backgrounds which feed-down from...
