Abstract

From a sample of 848±44 Ds+ππ+π+ decays, we find Γ(Ds+ππ+π+)/Γ(Ds+φπ+)=0.245±0.0280.012+0.019. Using a Dalitz plot analysis of this three body decay, we find significant contributions from the channels ρ0(770)π+, ρ0(1450)π+, f0(980)π+, f2(1270)π+, and f0(1370)π+. We also present the values obtained for masses and widths of the resonances f0(980) and f0(1370).
