The cross section of the process e+e-→K+K- was measured in the energy range s=1.04-1.38GeV 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 ρ, ω, and their lowest excitations. The mean statistical accuracy of the measurement is 4.4%, and the systematic uncertainty is 5.2%. © 2007 The American Physical Society.
