Abstract
We discuss phi production in ppBAR annihilation at rest from the Aster ix and Crystal Barrel experiments and compare the branching ratios to similar final states without strangeness. The omegapi0/phipi0 producti on ratio is unexpectedly low. In the search for new states, the phipi0 mass spectrum shows no evidence for a resonance in the 1450 MeV/c2 ma ss range but the KK0pi0 Dalitz plot shows interesting structure.
