Status of the CPT violating interpretations of the LSND signal
2003
We study the status of the CPT violating neutrino mass spectrum which has been proposed to simultaneously accommodate the oscillation data from LSND, KamLAND, atmospheric and solar neutrino experiments, as well as the non-observation of anti-neutrino disappearance in short-baseline reactor experiments. We perform a three-generation analysis of the global data with the aim of elucidating the viability of this solution. We find no compatibility between the results of the oscillation analysis of LSND and all-but-LSND data sets below 3$\sigma$ CL. Furthermore, the global data without LSND show no evidence for CPT violation: the best fit point of the all-but-LSND analysis occurs very close to a …
Search for Electron Antineutrino Appearance at theΔm2∼1 eV2Scale
2009
The MiniBooNE Collaboration reports initial results from a search for nu{sub m}u->nu{sub e} oscillations. A signal-blind analysis was performed using a data sample corresponding to 3.39x10{sup 20} protons on target. The data are consistent with background prediction across the full range of neutrino energy reconstructed assuming quasielastic scattering, 200<E{sub n}u{sup QE}<3000 MeV: 144 electronlike events have been observed in this energy range, compared to an expectation of 139.2+-17.6 events. No significant excess of events has been observed, both at low energy, 200-475 MeV, and at high energy, 475-1250 MeV. The data are inconclusive with respect to antineutrino oscillations suggested …
