Abstract

Precise measurements at $t = 0$ of the $K_{L} p \to K_{S} p$ amplitude (modulus and phase) were made. Over 50000 $K_{π 2}$ decays along with normalizing $K_{μ 3}$ events were detected behind a 7.2-m-long liquid-hydrogen regenerator. The momentum dependence of the modulus and phase are presented, and the results are combined with those of other experiments to extract the relevant parameters of $ω$ exchange.
