Hint ofCPTviolation in short-baseline electron neutrino disappearance data

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...

VSBL Electron Neutrino Disappearance

We consider possible indications of Very-Short-BaseLine (VSBL) electron neutrino disappearance into sterile neutrinos in MiniBooNE neutrino data and Gallium radioactive source experiments. We discuss the compatibility of such a disappearance with reactor and MiniBooNE antineutrino data. We find a tension between neutrino and antineutrino data which could be due to: 1) statistical fluctuations; ...

Matter effects in short-baseline neutrino oscillations

It is well known that matter effects in short-baseline oscillations of neutrino flavour are small and decrease with decreasing baseline more rapidly than the oscillations effects themselves. We discuss the reason for this and demonstrate that under certain circumstances this statement is no longer correct. In particular, we show that if neutrinos propagate significant distances in vacuum before...

Short Baseline Accelerator-based Neutrino Oscillation Searches

We review the status of the search for neutrino oscillations in the short baseline regime with experiments at accelerators. The evidence for ν̄μ→ ν̄e from the LSND experiment is compared with the negative results of the KARMEN ν̄μ→ ν̄e search and with the results from NOMAD and NuTeV in the same flavor mixing channel. We describe the upcoming MiniBooNE experiment which should be sufficiently sensit...
