英文摘要	A formalism is discussed that allows for a straightforward treatment of the relativistic three-body problem while keeping the correct analytic structure. In particular it is demonstrated that sacrificing covariance for analyticity can be justified by the hierarchy of different contributions in the spirit of an effective field theory. For definiteness the formalism is applied to the KK (K) over bar system allowing for the emergence of the a(0)(980) and the f(0)(980) as hadronic molecules. For simplicity all inelastic channels are switched off.
