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…

Measurements of the Branching Fractions and Decay Distributions for KL->πμνγand KL->πeνγ

T. Alexopoulos, T. Andre, M. Arenton +56

We present measurements of R_Kl3rad = Gamma(KL->π\ellνγ; Egcm > 10 MeV)/Gamma(KL->π\ellν), where ell = mu or e, and Egcm is the photon energy in the kaon rest frame. These measurem…

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) \…

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…
