New Measurement of theKSBranching Ratio

We have measured the ${K_S}^0$ charged-to-neutral branching ratio by examining ∼25 000 $K^{+}$ charge-exchange reactions in a Freon bubble chamber. Our result, 2.10 ± 0.06, is in poor agreement with a recent measurement by Gobbi et al. who obtained a value of 2.285 ± 0.055, while it is in fairly good agreement with the average of earlier experiments.
