Abstract
Using the complete KTeV data set of 5241 candidate decays (including an estimated background of events), we have measured the coupling of the conserving charge radius process and from it determined a charge radius of . We have determined a first experimental upper limit of 0.04 (90% C.L.) for the ratio of the couplings for the and direct photon emission processes. We also report the measurement of including a vector form factor , where and . Finally, a -violating asymmetry of in the and odd angle between the decay planes of the and pairs in the center of mass is reported.
