Detection of an electron neutrino (on the left) and an electron antineutrino (on the right) in the Super-Kamiokande detector.

Detection of an electron neutrino (on the left) and an electron antineutrino (on the right) in the Super-Kamiokande. When an electron neutrino or antineutrino interacts with water, an electron or a positron is produced. They emit a faint ring of light (called Cherenkov light) that is detected by almost 13,000 photodetectors. The colour on the figures shows how photons are detected over time.
