Abstract : Exactly solvable models of field theories are introduced and discussed. In some of these models the physical states involve an infinite number of bare particles. Some solutions are also found, which depend in a nonanalytic way on the coupling constant: these solutions may appear as new elementary particles. The field theoretical definition of elementary particle is then discussed. The renormalized coupling constants are always assumed to be smaller than some critical values (depending on the form factors of the models), thereby excluding any pathological feature (such as ghost states, etc.).
