This event was the first time that water had been used to detect a particle known as an antineutrino, which originated from a nuclear reactor more than 240 kilometers (150 miles) away. The ...

In around 13 out of every 100 billion kaon decays, however, the result is an antineutrino, a neutrino, and an unstable particle made of another flavor of quark and an antiquark called a pion.

Schematic of the antineutrino detector and reactors in the proposed area it is theoretically able to detect. Journalists may use this image only with appropriate credit and when reporting on this ...
