Abstract The photoproduction of the final state ω π+π−π0 has been studied as part of a survey of photoproduction in the energy range 20–70 GeV in the Omega spectrometer at CERN. The π+π−π0 system produced with the ω meson has a strongρ ± π ± component which is predominantlyI=1 andJ π=1+. For theωρ ±π∓ state a spin-parity analysis favoursJ π=1−, and the mass spectrum peaks at 2.28±0.05 GeV. The fitted width is Γ=0.44±0.11 GeV. The photoproduction cross-section of theωρ ±π∓ state, averaged over the energy range 25–60 GeV, is 150±50 nb.
