Abstract

Fermilab experiment E835 has studied reactions p̄p→π0π0, π0η,ηη, π0η′ and ηη′ in the energy region of the χc0(13P0) from 3340MeV to 3470MeV. Interference between resonant and continuum production is observed in the π0π0 and ηη channels, and the product of the input and output branching fractions is measured. Limits on resonant production are set for the π0η and π0η′ channels. An indication of interference is observed in the ηη′ channel. The technique for extracting resonance parameters in an environment dominated by continuum production is described.
