Abstract

A cross section of the process e+e−→π+π−π+π−has been measured using 6798 ±93signal events from a data sample corresponding to an integrated luminosity of 9.8pb−1collected with the CMD-3 detector in the center-of-mass energy range 920–1060MeV. 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
