Description

The comparison of neutral K-meson transition rates between flavour and CP eigenstates is used to perform independent tests of time-reversal T, CP and CPT symmetries. The analysis of 1.7 fb${}^{-1}$ of KLOE data acquired at the DA$\mathrm{\Phi }$NE $e^{+}{e}^{-}$ collider, using ratios of rates of the two classes of processes, $K_S{K}_L\to {\pi }^{\pm }{e}^{\mp }\nu ,3{\pi }^0$ and $K_S{K}_L\to {\pi }^{+}{\pi }^{-},{\pi }^{\pm }{e}^{\mp }\nu$, provides the first direct and model independent tests of T and CPT symmetries in transitions of neutral kaons.
