Abstract

The KTev experiment was performed at Fermilab to determine the Cabibbo-Kobayashi-Maskawa parameter |Vus| based on new measurements of the six largest KL branching fractions and semileptonic forms factors. The |Vus| was found to be equivalent to 0.2252±0. 0008KTeV±0.0021ext , where the errors were from KTeV measurements and from external sources. The CP violation parameter |η+-|=(2.228±0.005fKTeV±0.009 ext) ×10-3 was determined using the measured branching fractions. The results indicate that the improved form factor measurements may help to reduce theoretical uncertainties in f+(0).
