| dc.description | We present a determination of the CKM parameter |Vus| based on new measurements of the six largest KL branching fractions and semileptonic form factors by the KTeV (E832) experiment at Fermilab. We find |Vus| = 0.2252 +- 0.0008(KTeV) +- 0.0021(ext), where the errors are from KTeV measurements and from external sources. We also use the measured branching fractions to determine the CP violation parameter |eta+-| = [2.228 +- 0.005(KTeV) +- 0.009(ext)]E-3. | |
