In such decay, one of the two neutrons in a tritium nucleus turns into a proton and sends off a particle-antiparticle pair -- an electron and an electron antineutrino.
According to Fermilab physicist Dan Hooper, who is not part of MiniBooNE, the excess could be because muon antineutrinos turn into sterile neutrinos before becoming electron antineutrinos, reports The New Scientist.
These compounds emit light, or scintillate, when struck by fast-moving electrons such as those generated during complex reactions triggered when electron antineutrinos strike protons in the detector fluid.
In two runs, the second completed last November, the team detected 29 events indicating the presence of electron antineutrinos, which normally would be absent.
