Obsah

Experiment 865 at the Brookhaven Alternating Gradient Synchrotron obtained 410 K+→e+νe+e- and 2679 K+→μ+νe+e- events including 10% and 19% background. The branching ratios were measured to be [2.48±0.14(stat)±0.14(syst)]×10-8 (mee>150 MeV) and (7.06±0.16±0.26)×10-8 (mee>145 MeV), respectively. Results for the decay form factors are presented.
