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 òRmn Rmn 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.
