Abstract

The combined fitting of the e+e−→K+K− and KSKL cross sections in the energy range from threshold up to 2.15 GeV is done. The fit includes contributions from ρ, ω, ϕ mesons, and their radial and orbital excitations. As a result of the fit, the isovector and isoscalar contributions to the total cross section are obtained. The isovector part agrees with the spectral function, confirming CVC hypothesis.
