- And observing a decay mode with a branching ratio on the order of 3E - 11 requires a prodigious number of K-mesons in order to achieve the desired sensitivity.
- The number of these was small, about 0.3% of all decays, but has been confirmed in many experiments involving neutral K-mesons.
- The surprising feature, however, was something that was not seen: the neutral K-meson was never seen to decay into an electron and a positron.
- Scientists were expecting it to decay into a K-meson.

Origin
