在 VEPP-2M e + e - 对撞机的 SND 实验中，在能量范围 √s = 1.04-1.38 GeV 内测量了 e + e - → K + K - 过程的横截面。测量的横截面由矢量介子主导模型描述，其中包括光矢量介子 p、w、Φ 及其最低激发的贡献。测量的平均统计准确度为4.4%，系统不确定度为5.2%。
The cross section of the process e + e - → K + K - was measured in the energy range √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 p, w, Φ and their lowest excitations. The mean statistical accuracy of the measurement is 4.4%, and the systematic uncertainty is 5.2%.
