Observation of Direct CP Violation in Decays

…, M Arenton, K Arisaka, S Averitte, AR Barker… - Physical Review Letters, 1999 - APS
We have compared the decay rates of KL and KS to π+ π− and π 0 π 0 final states using a
subset of the data from the KTeV experiment (E832) at Fermilab. We find that the direct-CP-…
