Abstract
We present a determination of the Cabibbo-Kobayashi-Maskawa parameter based on new measurements of the six largest branching fractions and semileptonic form factors by the KTeV (E832) experiment at Fermilab. We find , where the errors are from KTeV measurements and from external sources. We also use the measured branching fractions to determine the CP violation parameter .
