First Measurement of Form Factors of the Decay Xi0->Sigma+ e- anti-nu/e
KTeV collaboration
We present the first measurement of the form factor ratios g1/f1 (direct axial-vector to vector), g2/f1 (second class current) and f2/f1 (weak magnetism) for the decay Xi0 -> Sigma…
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…
A Measurement of the Branching Ratio and Asymmetry of the Decay Cascade^0-->Sigma^0/gamma
A. Alavi-Harti
We have studied the rare weak radiative hyperon decay Cascade0-->Sigma0/gamma in the KTeV experiment at Fermilab. We have identified 4045 signal events over a background of 804 eve…
First Observation of the decay KL -> pi0 e e gamma
The KTeV Collaboration
We report on the first observation of the decay KL -> pi0 ee gamma by the KTeV E799 experiment at Fermilab. Based upon a sample of 48 events with an estimated background of 3.6 +/-…
A Measurement of the Branching Ratio of
The KTeV Collaboration, A. Alavi-Harati
We report on a study of the decay carried out as a part of the KTeV/E799 experiment at Fermilab. The 1997 data yielded a sample of 1543 events, including an expe…
Search for the Decay Kl -> pi0 e+ e-
A. Alavi-Harati
We report on a search for the decay Kl -> pi0 e+ e- carried out by the KTeV/E799 experiment at Fermilab. This decay is expected to have a significant CP violating contribution and…
Search for the Decay
A. Alavi-Harati
We report on a search for the decay \klpimumu carried out as a part of the KTeV experiment at Fermilab. This decay is expected to have a significant violating contribution and…
Observation of the Decay
A. Alavi-Harati
We have observed the decay at the KTeV experiment at Fermilab. This decay presents a formidable background to the search for new physics in . Th…
Search for the Weak Decay of a Lightly Bound H Dibaryon
The KTeV Collaboration
We present results of a search for a neutral, six-quark, dibaryon state called the \h, a state predicted to exist in several theoretical models. Observation of such a state would s…
Measurement of the branching ratio of pi^0 -> e^+e^- using K_L -> 3 pi^0 decays in flight
KTeV Collaboration
The branching ratio of the rare decay pi^0 -> e^+e^- has been measured in E799-II, a rare kaon decay experiment using the KTeV detector at Fermilab. The pi^0's were produced in ful…
Measurement of the Decay KL -> Pi0 Gamma Gamma
A. Alavi-Harati et. al, the KTeV Collaboration
We report on a new measurement of the decay KL -> pi0 gamma gamma by the KTeV experiment at Fermilab. We determine the KL -> pi0 gamma gamma branching ratio to be (1.68 +/- 0.07 +/…
