Abstract

We present recent preliminary results from five decay channels. From the KLπ+πγK_L\to\pi^+\pi^-\gamma channel, we extract form factors for the CP violating M1 direct photon emission amplitude and the fraction of the total decay amplitude that is due to direct emission. We have placed an upper limit on the KLπ0π0γK_L\to\pi^0\pi^0\gamma branching ratio, and preliminary measurements of the KLπ±eνe+eK_L\to\pi^{\pm}e^{\mp}\nu e^+e^- and π0e+e\pi^0\to e^+e^- branching ratios are presented. Finally, we report measurements of both the branching ratio and the form factor parameters for the decay KLe+eγK_L\to e^+e^-\gamma.
