摘要在质心能量1004-1060Me V之间的25个能量点测量了e^+e^-→K_S^0+K_L^0和e^+e^-→KK截面,系统误差大约为2%-3%.分析是基于VEPP-2000e^+e^-对撞机上CMD-3收集的积分亮度为5.5 pb-1的实验数据.测量的截面可近似看作Ф,ω,ρ类似的振幅及其激发态按照矢量介子主导模型的叠加,得到了Ф(1020)介子的共振参数. The e^+e^-→K_S^0K_L^0 and e+e-→K-K+cross sections have been measured in the center-of-mass energy range 1004-1060 Me V for 25 energy points with about 2%-3% systematic uncertainties. The analysis is based on 5. 5 pb^(-1) of integrated luminosity collected with the CMD-3 detector at the VEPP-2000 e^+e^-collider. The measured cross section is approximated according to vector meson dominance model as a sum of Ф,ω,ρ-like amplitudes and their excitations,and Ф( 1020) meson parameters have been obtained.
