Abstract

We present a branching ratio measurement for the beta decay of neutral Cascade hyperon to a positive Sigma, electron and neutrino. Data were collected during 1997 with the KTeV detector at Fermilab. We used the principal decay mode, Cascade to a Lambda and a neutral pion, as the flux normalization mode. The status of the measurement of the ratio of the axial-vector to vector coupling (g₁/f₁) for this decay will also be discussed. Furthermore, we present the preliminary branching ratio measurement for the muonic channel of Cascade beta decay.
