摘要：
An integrated luminosity approximate to 4000 nb(-1) of around phi meson mass (5.0 x 10(6) of phi's) has been collected with the CMD-2 detector at the VEPP-2M collider. The latest analysis of the KSKL coupled decays based on 30% of available data is presented in this paper. The KSKL pairs from phi decays were reconstructed in the drift chamber when both kaons decayed into two charged particles. From a sample of 1423 coupled decays a selection of candidates for the CP-violating K-L --> pi(+)pi(-) decay was performed. CP-violating decays were not identified because of the dominance of events with a K-L regenerating at the Be beam pipe into K-S and a background from K-L semileptonic decays. The regeneration cross section of 110 MeV/c K-L's was found to be sigma(reg)(Be) = 53 +/- 17 mb, in agreement with theoretical expectations. The angular distribution of K-S's after regeneration and the total cross section of K-L for Be have been measured. (C) 1997 Published by Elsevier Science B.V.
