(2018). Study of the process e+e− → K+K− in the center-of-mass energy range 1010–1060 MeV with the CMD-3 detector. Physics Letters B, 779, 64-71. https://doi.org/10.1016/j.physletb.2018.01.079https://doi.org/10.1016/j.physletb.2018.01.079http://hdl.handle.net/1828/10183The 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.enVictoria Subatomic Physics and Accelerator Research Centre (VSPA)ArticleDepartment of Physics and Astronomy
