Observation of the decay KL 0 →e+e-e+e-

Two events with the characteristics of the decay KL0 →e+e-e+e- have been observed with a negligible expected background from which a branching ratio of (4 ± 3) X 10-8 is derived. This result is consistent with values estimated from theoretical models based on the double internal conventional of the...
