We present two models of relativistic interactions in quantum mechanics that produce resonances. In both cases, these resonances are described by poles of the analytic continuations of Green functions in terms of the variable energy. We develop the first model in detail and motivate and describe the second one. We compare the common features between these two models. The analysis is made in the context of quantum field theory.
