Cascade and anti-Cascade Polarization Measurements at 800 GeV/c
KTeV Collaboration
The polarization of neutral Cascade and anti-Cascade hyperons produced by 800 GeV/c protons on a BeO target at a fixed targeting angle of 4.8 mrad is measured by the KTeV 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…
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…
Branching Ratio Measurement of the decay K_L -> e+ e- mu+ mu-
Alavi-Harati
We have collected a 43 event sample of the decay with negligible backgrounds and measured its branching ratio to be .…
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…
