In this paper we discuss the recent finalized analyses by the KLOE experiment at DA$Phi$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 ${ K^+} rightarrow pi^+pi^-pi^+(gamma)$. We also present the status of an ongoing analysis aiming to precisely measure the $K^{pm} $ mass.
Kaon physics can test new-physics effects in leptonic or semileptonic decays. A unitarity test of the first row of the CKM mixing matrix is obtained from the precision measurements of Kl3 widths for K{pm}, KL, and (unique to KLOE) KS. The KLOE measur
We describe the KLOE detector at DAFNE, and its physics program. The impact of our results on flavor and hadron physics to date, as well as an outlook for further improvement in the near future, are discussed.
All relevant inputs for the extraction of the CKM matrix element vus from kl, ks and kpm decays have been measured at KLOE. From a global fit using only KLOE results, but ks lifetime, a value of $|vus|fzero = 0.2157 pm 0.0006$ is obtained, where fzer
We have measured the charged kaon lifetime using a sample of 15 times 10^6 tagged kaon decays. Charged kaons were produced in pairs at the DAPhiNE phi-factory, e^+e^- to phi to K^+ K^-. The decay of a K^+ was tagged by the production of a K^- and vic
The phi-factory DAPHNE offers a possibility to select pure kaon beams, charged and neutral ones. In particular, neutral kaons from phi->KS KL are produced in pairs and the detection of a KS (KL) tags the presence of a KL (KS). This allows to perform
