Abstract
On the basis of a Chern-Simons field-theoretical description we propose a simple method for the derivation of model interactions for Pfaffian paired states. We verify the method in the case of the Pfaffian (i.e., Moore-Read) state and derive a general form of the model interaction in the case of the particle-hole (PH) Pfaffian. More than one Landau level is needed to establish the correlations of the PH Pfaffian, and we present the values of relevant three-body pseudopotentials for two Landau levels.
