KTeV results: Re(e'/e) and rare decay results
The KTeV physics program encompasses many goals including a precision measurement of the direct CP violation parameter Re({epsilon}{prime}/{epsilon}) in K{sub S,L} {yields} {pi}{pi} decays, and studies of rare neutral kaon decays. The KTeV detector collected data during the Fermilab fixed-target runs of 1996-97 and 1999. This article focuses on the precision measurement of the direct CP violation parameter Re({epsilon}{prime}/{epsilon}) using the 1996-97 data set. In addition, measurements of the neutral kaon parameters {tau}{sub s}, {Delta}m, {phi}{sub {+-}}, {Delta}{phi} from that data set and a new measurement of the branching fraction of K{sub L} {yields} e{sup +}e{sup -} {mu}{sup +}{mu}{sup -} from the 1997 and 1999 data also are presented.
