Recent results from the CMD-2 detector at VEPP-2M collider

Solodov E. P.

The general purpose detector CMD-2 is taking data at the e+e- collider VEPP-2M at Novosibirsk in the energy range 360 -1400 MeV. The integrated luminosity ≈ 4000nb-1 of around φ meson mass (5.0 × 106 of φ's) and ≈ 500nb-1 in the 600-1000 MeV range have been collected. A latest analysis of the rare decays of φ meson and the KSKL coupled decays based on 30% of available data is presented in this paper. A selection of KL → π+π- decays demonstrated background from semileptonic KL decays and the regeneration of KL into KS at the Be vacuum pipe. The regeneration cross section for 110 MeV/c kaons has been measured along with angular distribution.
