By measuring the neutrinosand their antimatter partners, antineutrinos, in both locations, physicists can study how these particles change their type as they travel, a phenomenon known as neutrino oscillation.

From Science Daily

Sitting still, a muon decays into an electron, a neutrino, and an antineutrino in 2.2 microseconds.

From Science Magazine

For years it seemed like building a muon collider might be the only way to answer whether neutrinos behave differently than antineutrinos.

From Scientific American

As the electron antineutrinos travel from the reactors to JUNO, many will oscillate into muon or tau antineutrinos that the detector can’t see.

From Science Magazine

In this study, my collaborators and I proved that this new measurement of helium is consistent with there being more neutrinos then antineutrinos in the early universe.
