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$\Phi$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.
