MEASUREMENT OF THE BRANCHING RATIO OF THE DOUBLE DALITZ DECAY K-L-]E(+)E(-)E(+)E(-) AND THE CP PARITY OF THE K-L-MESON

Data from the NA31 experiment at CERN have been used to measure the branching ratio of the double Dalitz decay of the long-lived neutral kaon. Eight events have been found with negligible background. The measured distribution of the angle between the planes of the two e+e--pairs favours a CP=-1 stat...
