Amsterdam: Elsevier B.V., v. 495, n. 3-4, p. 394-400, 2000.0370-2693http://hdl.handle.net/11449/23362An algorithm for computing the propagator for three-dimensional quadratic gravity with a gravitational Chern-Simons term, based on an extension of the three-dimensional Barnes-Rivers operators, is proposed. A systematic study of the tree-level unitarity of this theory is developed and its agreement with Newton's law is investigated by computing the effective nonrelativistic potential.
