Rare kaon decay recorded: new horizons in physics

Scientists from CERN have made a significant discovery studying the rarest decay of a subatomic particle, the kaon. In the framework of experiment NA62 was recorded this phenomenon, called the “golden channel”, in less than one case out of 10 billion kaons.

The decay process involves the transformation of a charged kaon into three other particles: a charged pion, a neutrino and an antineutrino.
