Abstract

Tests of the discrete symmetries

P

,

C

,

CP

, and

T

are obtained through comparison of the rare decays

K^{\pm} \to π^{+} π^{-} e^{\pm} ν_{e}

(

K_{e 4}

decays). An important outgrowth of the experiment is a direct measurement of the low-energy pion-pion relative scattering phase,

δ_{0} - δ_{1}

.
