The reaction pp → pf(π+ π- π0)ps has been studied at 450 GeV/c in an experiment designed to search for gluonic states. A spin analysis has been performed and the dPT filter applied. The analysis confirms the previous observation that all undisputed qq̄ states are suppressed at small dPT. In addition, a clear difference is observed in the production mechanism for the η and ω.
