The antiparticle to the neutrino; it has zero mass, spin ½, and positive helicity; there are two antineutrinos, one associated with electrons and one with muons.

Pions decay into muons and muon neutrinos, and the muons, in turn, transform into positrons, electron neutrinos, and muon antineutrinos. A tiny fraction of the neutrinos collide with atomic nuclei in a nearby detector, which consists of a large tank of mineral oil surrounded by an array of photodetectors.
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.
Over about half a kilometer, muon antineutrinos morphed into electron antineutrinos more often than muon neutrinos became electron neutrinos.
