Titled "Observation of a Significant Excess of Electron-Like Events in the MiniBooNE Short-Baseline Neutrino Experiment," the paper's abstract says: "The MiniBooNE data are consistent in energy and magnitude with the excess of events reported by the LSND."
It also says that by itself, the MiniBooNE data has a 4.8-sigma, and combined with the LSND data, the events detected in the two experiments that could suggest the existence of a yet-unknown particle have a 6.1- sigma.
While MiniBooNE used neutrinos to find the sterile neutrino,
LSND used antineutrinos - the antimatter equivalent.
However, solar and atmospheric experiments indicate mass differences among neutrinos incompatible with the
LSND findings.
Considering limits set by the
LSND's sensitivity, the neutrino's mass appears to be at least 0.5 electronvolt.
We finally test the compatibility of the employed NSI scenario with recent results from the
LSND and MiniBooNE experiments.
The KARMEN experiment [56] was another player in this debate, but on the other side, since it did not detect the same hints of
LSND and MiniBooNE.
The liquid scintillator neutrino detector (
LSND) collaboration implied that gave sterile neutrinos comes from the unconfirmed observation on [v.sub.[mu]] [right arrow] [v.sub.s] [37-39].
A search for [v.sub.[mu]] [right arrow] [v.sub.e] appearance at high [DELTA][m.sup.2], hence short-baseline, can be performed to address the
LSND [61] and MiniBooNE [78] signals if the DAE[delta]ALUS configuration uses a large scintillator detector such as LENA [75].
Section 5.1 is dedicated to the
LSND [DELTA][m.sup.2] scale and to a discussion of new proposals on the subject of sterile neutrinos.
Few experimental results cannot be accommodated in this framework: the
LSND anomaly [21] (further investigated by MiniBooNE [22]) as well as a possible neutrino deficit observed in reactor [23] and Gallium measurements with very intense (Mci) radioactive neutrino sources [24].
Experimental studies using the probability (7) have been performed by Double Chooz [50], IceCube [51],
LSND [52], MiniBooNE [53, 54], and MINOS using its near detector [55, 56].
