Abstract

A search for the reactions γγ→ωω and γγ→ρ0ω has been carried out at an average e+e- CM energy of 34.6 GeV with an integrated luminosity of 45 pb-1. Upper limits are set for these two channels over the γγ CM Energy range of 1.6 to 2.5 GeV. The cross section is determined for the exclusive channel γγ→π+2 π-π0.
