Abstract: (APS)
A Euclidean lattice formulation is presented of the general fourth-order gravitational action involving Rμν2 terms. This lattice theory is bounded and reflection positive. The existence of a positive Hilbert space and Hamiltonian, and hence unitarity, follow then from the standard nonperturbative Osterwalder-Schrader construction.
