dc.description.abstractThe process e+e−→K+K−has been studied using 1.7 ×106events from a data sample corresponding to an integrated luminosity of 5.7 pb−1collected with the CMD-3 detector in the center-of-mass energy range 1010–1060 MeV. The cross section is measured with about 2% systematic uncertainty and is used to calculate the contribution to the anomalous magnetic moment of the muon aK+K−μ=(19.33 ±0.40) ×10−10, and to obtain the φ(1020)meson parameters. We consider the relationship between the e+e−→K+K−and e+e−→K0SK0Lcross sections and compare it to the theoretical prediction.en_US
