Study of the centrally produced ωρ0 and ωω systems inpp interactions at 300 GeV/c

We have performed a search for vector-vector final states centrally produced in proton proton interactions at 300 GeV/c using the CERN Ω spectrometer. Evidence is found for ωρ0 production in the reactionpp→p f (2π+2π−2π0)p s and for ωω production in the reactionpp→p f (2π+2π−2π0)p s . However no evidence is found for ωo production in the reactionpp→p f (K + K −π+π−π0)p s .
