Kaon Physics with the KLOE Detector

Abstract

In this paper, we discuss the recent finalized analyses by the KLOE experiment at DAΦNE: the CPT and Lorentz invariance test with entangled K 0K 0 pairs, and the precision measurement of the branching fraction of the decay K + → π + π − π + (γ). We also present the status of an ongoing analysis aiming to precisely measure the K ± mass.
