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) ×10−6enVictoria Subatomic Physics and Accelerator Research Centre (VSPA)ArticleDepartment of Physics and Astronomy
