Branching ratios have been determined for the f0 meson produced in 4 GeV/c π+d interactions. The decay rates to 2π+2π− and KK are 2.4 ± 0.6% and 2.5 ± 1.5% respectively, both relative to the ππ mode. Upper limits are given for the decays to

The production of strange particles in π + d interactions has been examined at 4 GeV/ c where no previous data exist. Careful attention has been given to the resolution of ambiguities and to corrections for losses in a total sample of about 22 000 e

We compare new data on π+n → ϱop and π+n → ωop at 4 GeV/c with single-pion photoproduction data. Good agreement is obtained with the predictions of the vector dominance model from unpolarized photoproduction data. However, in the forward dire
