We construct the two– and three–nucleon potential based on the most general chiral effective pion–nucleon Lagrangian using the method of unitary transformations. For that, we develop a power counting scheme consistent with this projection formalism. In contrast to previous results obtained in old–fashioned time–ordered perturbation theory, the method employed leads to energy–independent potentials. We discuss in detail the similarities and differences to the existing chiral nucleon–nucleon… CONTINUE READING
