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…
A Measurement of the KL Charge Asymmetry
The KTeV Collaboration, A. Alavi-Harati
We present a measurement of the charge asymmetry in the mode based on 298 million analyzed decays. We measure a value of $δ_L = (3322 \pm 58(stat) \…
Radiative Decay Width Measurements of Neutral Kaon Excitations Using the Primakoff Effect
KTeV Collaboration, A. Alavi-Harati
We produce a sample consisting of 147 candidate events, with minimal backgrounds, of the mixed axial vector pair K1(1270)-K1(1400) by exciting Kl's in the Coulomb field of lead and…
A New Measurement of the Radiative Ke3 Branching Ratio and Photon Spectrum
Douglas R. Bergman
We present a new measurement of the branching ratio of the decay K_L -> pi e nu gamma (Ke3g) with respect to K_L -> pi e nu (Ke3), and the first study of the photon energy spectrum…
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…
