Measurement of the e+e- -> K+K- cross section in the energy range s**(1/2) = 1.04 - 1.38 GeV with the SND detector in the experiment at the VEPP-2M e+e- collider

Abstract

The cross section of the process $e^{+}{e}^{-}\to K^{+}{K}^{-}$ was measured in the energy range $\sqrt{s}$ = 1.04--1.38 GeV in the SND experiment at the VEPP-2M $e^{+}{e}^{-}$ collider. The measured cross section is described by the model of vector meson dominance with contributions from the light vector mesons $\rho$, $\omega$, $\varphi$ and their lowest excitations. The mean statistical accuracy of the measurement is 4.4 %, and the systematic uncertainty is 5.2 %.
