Improved $K_{\rm S}$ Tagging Procedure and Its Impact on Physics at KLOE-2

Abstract

The KLOE experiment at the DAΦNE φ-factory performed precise studies of charged and neutral kaon physics, low energy QCD, as well as tests of CP and CPT invariance. For the new run the KLOE has been upgraded by adding new tagger systems for the γγ physics, the inner tracking chamber and two calorimeters in the final focusing region. We are also improving on kaon identification techniques, in particular algorithms for the K S meson tagging. In this article we discuss the impact of the improved tagging procedure on studies of the K S decays.

Search for the $U$ Boson in the Process $e^+e^- \to \mu ^+ \mu ^- \gamma $, $U \to \mu ^+\mu ^-$ with the KLOE Detector

“…In this paper, we focus the discussion on the two most recent results on kaon physics: a CPT and Lorentz invariance test with entangled K 0 K0 pairs, and the precision measurement of the branching fraction of the decay K + → π + π − π + (γ). Among the ongoing analyses, there are: The status of analysis (a) is also presented in this paper, while (b), (c) and (d) are the subjects of separate contributions in this issue [2][3][4].…”
