Abstract. In the one-particle sector of Nelson's massless model, the one-particle
states are constructed for an arbitrarily small infrared cut-off in the
interaction term of the Hamiltonian of the System. The performed method
is a constructive one which exploits only regular perturbation theory, by
a suitable iteration scheme. The disappearance of one-particle states is
showed in the limit of no infrared regularization. Constructive features,
as regularity in some parameters, are also inquired.
