Аннотация

A preliminary result of an analysis of the process (Formula presented.) whose cross section was measured in the range of center-of-mass collision energies between 1.2 and 2 GeV is presented. The analysis is based on the data sample corresponding to an integrated luminosity of about 120 pb-1 accumulated with the CMD-3 detector at the VEPP-2000 electron–positron collider. A procedure for separating signal events is developed, and the dominance of the K*(892)K neutral mode is confirmed. The cross section for the process (Formula presented.) is measured to a precision higher than that in earlier experiments. This permits improving the accuracy in measuring the mass and width of the φ(1680) meson, testing the accuracy of the isotopic relations, and more accurately calculating the hadronic contribution to the muon anomalous magnetic moment (g-2).
