This paper reviews the results of the LSND and MiniBooNE experiments. The primary goal of each experiment was to effect sensitive searches for neutrino oscillations in the mass region with ∆m 2 ∼ 1 eV 2 . The two experiments are complementary, and so the comparison of results can bring additional information with respect to models with sterile neutrinos. Both experiments obtained evidence forνµ →νe oscillations, and MiniBooNE also observed a νµ → νe excess.In this paper, we review the design, analysis, and results from these experiments. We then consider the results within the global context of sterile neutrino oscillation models. The final data sets require a more extended model than the simple single sterile neutrino model imagined arXiv:1306.6494v1 [hep-ex] 27 Jun 2013 at the time that LSND drew to a close and MiniBooNE began. We show that there are apparent incompatibilities between data sets in models with two sterile neutrinos. However, these incompatibilities may be explained with variations within the systematic error. Overall, models with two (or three) sterile neutrinos seem to succeed in fitting the global data, and they make interesting predictions for future experiments.

“…The exclusive and inclusive charged-current reactions 12 C(ν e , e − ) 12 N have been measured by the KARMEN and LSND collaborations for neutrinos generated by muon decay at rest [1][2][3][4]. The KARMEN collaboration has supplemented this by a measurement of the neutral current 12 C(ν, ν ′ ) 12 C * (15.11 MeV) cross section [5]. Using the LAMPF pion-decay-in-flight neutrino source, the LSND collaboration has also measured the 12 C(ν µ , µ − ) 12 N cross section [6].…”

Weak reactions on 12C within the continuum random phase approximation with partial occupancies

We extend our previous studies of the neutrino-induced reactions on 12 C and muon capture to include partial occupation of nuclear subshells in the framework of the continuum random phase approximation. We find, in contrast to the work by Auerbach et al., that a partial occupation of the p 1/2 subshell reduces the inclusive cross sections only slightly. The extended model describes the muon capture rate and the 12 C(ν e , e − ) 12 N cross section very well. The recently updated flux and the improved model bring the calculated 12 C(ν µ , µ − ) 12 N cross section (≈ 17.5 · 10 −40 cm 2 ) and the data ((12.4±0.3(stat.)±1.8(syst.)·10 −40 cm 2 ) closer together, but does not remove the discrepancy fully. 25.30.PtTypeset using REVT E X

Limits on electron neutrino disappearance from the KARMEN and LSNDνe-carbon cross section data

This paper presents a combined analysis of the KARMEN and LSND νe-carbon cross section measurements within the context of a search for νe disappearance at high ∆m 2 . KARMEN and LSND were located at 17.7 m and 29.8 m respectively from the neutrino source, so, the consistency of the two measurements, as a function of antineutrino energy, sets strong limits on neutrino oscillations. Most of the allowed region from the νe disappearance analysis of the Gallium calibration data is excluded at >95% CL and the best fit point is excluded at 3.6σ. Assuming CPT conservation, comparisons are also made to the oscillation analyses of reactor antineutrino data.
