Description

The combined fitting of the e+e-→K+K- and KSKL cross sections in the energy range from KK-bar 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 e+e-→KK-bar cross section are obtained. The isovector part agrees with the τ→KK-bar ν spectral function, confirming CVC hypothesis
