Recent Results from the KTeV Experiment
Wilking, M. J.
Original · EN
We present recent preliminary results from five decay channels. From the Kₗ→π+π-γ 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 Kₗ→π⁰π⁰γ branching ratio, and preliminary measurements of the Kₗ→π±e∓νe+e- and π⁰→ e+e- branching ratios are presented. Finally, we report measurements of both the branching ratio and the form factor parameters for the decay Kₗ→ e+e-γ.
