We consider weakly coupled even λP(Φ)2 models that do not have a two-body bound state, and prove asymptotic completeness on the subspace of states with mass between 3m+a(λ) and 4m−b(λ), wherea andb are positive functions tending to zero with λ. The analytic structure of the six point function, integrated over the three incoming momenta, shows only two Landau singular manifolds (plus normal thresholds) associated to three particle processes.
