| الوصف: | A ��-factory offers the possibility to select pure kaon beams. Neutral kaons from �� ��� KSKL are produced in a pure J PC = 1- quantum state. Detection of a kaon at large (small) times tags a KS (KL). This allows to perform precise measurement of kaon properties, as for example lifetime, and to study time evolution of neutral kaon system. The distribution of ��t, the difference between the two neutral kaon decay times, where both kaons decay into a ��+��- pair, provides unique opportunities for testing quantum mechanics and CPT symmetry. Using the full 2004-2005 data sample (L = 1.5fb-1) collected with the KLOE detector at DAF��NE, the Frascati e+e- collider, we update results of quantum mechanics and CPT invariance tests. We are finalizing the determination K S lifetimes using about 1/3 the whole KLOE data set. The proper time distribution of KS ��� ��+��- decays provides a competitive measurement of KS meson lifetime. �� Copyright owned by the author(s) under the terms of the Creative Commons Attribution-NonCommercial-ShareAlike Licence. |
