Measurement of the Decay KL -> pi0 e+ e- gamma
KTeV Collaboration, E. Abouzaid, M. Arenton +48
We report on a new measurement of the branching ratio B(KL -> pi0 e+ e- gamma) using the KTeV detector. This analysis uses the full KTeV data set collected from 1997 to 2000. We re…
Observation of the Decay Xi^0 --> Sigma^+ mu^- nu(bar)
KTeV Collaboration, E. Abouzaid, T. Alexopoulos +57
The Xi^0 muon semi-leptonic decay has been observed for the first time with nine identified events using the KTeV beam line and detector at Fermilab. The decay is normalized to the…
A Determination of the CKM Parameter |Vus|
KTeV Collaboration, T. Alexopoulos
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) experimen…
Search for the K(L) --> PI0 PI0 E+ E- Decay in the KTeV Experiment
KTeV Collaboration, A. Alavi-Harati
The recent discovery of a large CP violating asymmetry in K(L) --> PI+ PI- E+ E- mode has prompted us to seach for the associated K(L) --> PI0 PI0 E+ E- decay mode in the KTeV-E799…
Recent KTEV Results
R. Kessler
Preliminary KTEV results are presented based on the 1997 data set, and include an improved measurement of Re(e'/e), CPT tests, and precise measurements of Tau_S and Delta M.
Measurements of the rare decay K_{L} -> e^{+} e^{-} e^{+} e^{-}
The KTeV Collaboration, A. Alavi-Harati
We observe 441 K_{L} -> e^{+} e^{-} e^{+} e^{-} candidate events with a background of 4.2 events and measure B(K_{L} -> e^{+} e^{-} e^{+} e^{-}) = (3.72 \pm 0.18(stat) \pm 0.23(sys…
