ACCIOLY, A.; RAGUSA, S.; MUKAI, H.  and  REY NETO, E. de. Fierz-Pauli higher derivative gravity. Braz. J. Phys. [online]. 2000, vol.30, n.3, pp. 544-553. ISSN 0103-9733.  http://dx.doi.org/10.1590/S0103-97332000000300011.

We consider a model for gravity in which the linear part of the four-derivative terms òR_mn R^mn d⁴ x and òR² d⁴ x are included into the Fierz-Pauli gravitational action. Unitarity is discussed at the tree-level. The issue of the gravitational deflection of a light ray is also considered.
