Abstract

In an experiment at the Princeton-Pennsylvania Accelerator, the relative rate

\frac{{K_{e 2}}^{+}}{{K_{μ 2}}^{+}}

was measured to be (

{1.8}_{- 0.6}^{+ 0.8}

) ×

10^{- 5}

. Combining this with previous measurements gives a world average of (

{1.9}_{- 0.4}^{+ 0.5}

) ×

10^{- 5}

, which agrees with the universal

V - A

theory prediction of 2.09 ×

10^{- 5}

.
