First measurement of branching ratio and g1/f1 of the neutral cascade hyperon using final state polarization
Creators
Description
The KTeV collaboration has made a first observation of neutral cascade beta decay (Ξ0 → Σ+ e- nbar). We present measurements of the branching ratio and form factors for this semi leptonic process. The results agree well with the Cabibbo SU(3)f theory and do not favor attempts to include symmetry breaking effects
