A new measurement of CP violation parameter. var epsilon. prime /. var epsilon

Conference ·
OSTI ID:7273944
The E731 experiment at Fermilab has measured the CP violation parameter Re({var epsilon}{prime}/{var epsilon}) in K{sub L,S}{yields}{pi}{pi} decay. Four decay modes were collected simultaneously to reduce systematic errors. The result is Re({var epsilon}{prime}/{var epsilon})={minus}0.0005 {plus minus} 0.0014 (stat.) {plus minus} 0.0006 (syst.), and gives no evidence for direct CP violation. 7 refs., 3 figs., 1 tab.
