Abstract
Abstract The clothed particle formalism is shown to be of no practical use as it leads either to an incomplete current or to a non-local field theory which violates not only the locality condition but also the Yang-Feldman equation. A short proof is given of the statement that neither the current nor the Heisenberg field can be expressed as a polynomial (in a generalized sense) in the incoming (or outgoing) fields. This statement is based on the assertion of O.W. Greenberg that the outgoing field cannot be expressed as a polynomial with respect to the incoming fields unless both fields coincide.
