Measurement of the e+e− → ηK+K− Cross Section by Means of the SND Detector

Measurement of the e+e−→π+π−π0η cross section below Ачасов1, Barnyakov2, Beloborodov3 et al. 2019Phys. Rev. D

“…The model parameters obtained in the fit are used to calculate δðĒ i Þ using Eq. (10). HereĒ i is the weighted average c.m.…”

“…The e þ e − → ωη cross section was previously measured in the BABAR [5], SND [6], and CMD-3 [4] experiments. The e þ e − → ϕη process was studied in the BABAR experiment in several ϕ and η decay modes [7][8][9], and in the SND experiment in the K þ K − γγ final state [10]. The study of the e þ e − → π þ π − π 0 η process was performed by the CMD-3 detector [4], which measured for the first time the total e þ e − → π þ π − π 0 η cross section in the energy region E < 2 GeV and the cross sections for the subprocesses (4) and (5).…”

“…2) are compatible with previous (BABAR) measurements [3] and have comparable accuracy. The known mechanism of the process is e + e − → φ (1680) → ηφ → ηK + K − , no other significant mechanism were found [4].…”
