A NEW MEASUREMENT OF DIRECT CP VIOLATION IN THE NEUTRAL KAON SYSTEM

A new measurement of the ratio of the CP-violating amplitudes for KL → 2π0 and KL → π+π- is reported. The measured value for R = {divides}η00/η+-{divides}2 is 0.9878±0.0026±0.0030, where the first error is the statistical uncertainty and the second is the estimate of the systematic uncertainty.
