Study of the vector-vector final states centrally produced in pp interactions at 300 GeV/c

We have performed a search for vector-vector final states centrally produced in the reaction pp→pf(VV)ps at 300 GeV/c using the CERN Ω spectrometer. Evidence is found for ωπ0, ωω, π0π0 and π+π- associated production. No evidence is found for ωϕ production.
