Kaon physics with the KLOE detector

Abstract

In this paper we discuss the recent finalized analyses by the KLOE experiment at DA$\hat{I}¦$NE: the CPT and Lorentz invariance test with entangled $K^0{\bar{K}}^0$ pairs, and the precision measurement of the branching fraction of the decay $K^{+}\to \ddot{I}{€}^{+}\ddot{I}{€}^{-}\ddot{I}{€}^{+}({\hat{I}}^3)$. We also present the status of an ongoing analysis aiming to precisely measure the $K^{\pm }$ mass.
