The Born cross sections are measured and the ratio of the cross sections σ(e⁺e⁻ → φφω)/σ(e⁺e⁻ → φφφ) is estimated to be 1.75 ± 0.22 ± 0.19 averaged over six energy points, where the first uncertainty is statistical and the second is systematic. The results represent first measurements of these interactions.enCC BY 4.0 (Attribution)©2017 The Authorshttp://creativecommons.org/licenses/by/4.0/QuarkoniumsAnnihilation (Nuclear reactions)Electron-positron interactionsMeasurement of Cross Sections of the Interactions e⁺e⁻ → φφω and e⁺e⁻ → φφφ at Center-Of-Mass Energies from 4.008 to 4.600 GeVarticleAblikim, M., M.
