The neutral kaon system offers a unique possibility to perform fundamental tests of CPT invariance. In this contribution the KLOE prospects for the measurements of CPT violation in the context of the Standard-Model Extension are presented. Preliminary results on the CPT violating parameters already obtained by KLOE analyzing only half of the available data with a simplified analysis scheme will be reported: Î” a X = (âˆ’6.3Â±6.0) Ã— 10 âˆ’18 GeV, Î” a Y = (2.8 Â± 5.9) Ã— 10 âˆ’18 GeV, Î” a z = (2.4 Â± 9.7) Ã— 10 âˆ’18 GeV. In this contribution we will discuss a new analysis method that will allow to measure the complete set of four parameters (Î” a ÎŒ ) also with the perspective given by the KLOE-2 data-taking campaign.
