Аннотация

A cross section of the process e⁺e⁻→π⁺π⁻π⁺π⁻ has been measured using 6798±93 signal events from a data sample corresponding to an integrated luminosity of 9.8 pb⁻¹ collected with the CMD-3 detector in the center-of-mass energy range 920–1060 MeV. The measured cross section exhibits a pattern of interference of the ϕ(1020)→π⁺π⁻π⁺π⁻ decay with a non-resonant process e⁺e⁻→π⁺π⁻π⁺π⁻, from which we obtain the branching fraction of the doubly suppressed decays (by G-parity and OZI rule): B(ϕ→π⁺π⁻π⁺π⁻)=(6.5±2.7±1.6)×10⁻⁶.
