Status and prospects for Lorentz and CPT violation tests at KLOE and KLOE-2

• 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: Δ a X = (−6.3±6.0) × 10 −18 GeV, Δ a Y = (2.8 ± 5.9) × 10 −18 GeV, Δ a z = (2.4 ± 9.7) × 10 −18 GeV. In this contribution we will discuss a new analysis method that will allow to measure the complete set of four parameters (Δ a ÎŒ ) also with the perspective given by the KLOE-2 data-taking campaign.
