| dc.description | The wave function for the quadratic gravity theory derived from the heterotic string effective action is deduced to first order in ${e^{-Φ}\over {g_4^2}}$ by solving a perturbed second-order Wheeler-DeWitt equation, assuming that the potential is slowly varying with respect to $Φ$. Predictions for inflation based on the solution to the second-order Wheeler-DeWitt equation continue to hold for this theory. It is shown how formal expressions for the average paths in minisuperspace $\{< a(t) >, < Φ(t)> \}$ determine the shifts from the classical solutions to $a_{cl}(t)$ and $Φ_{cl}(t)$, which occur only at third order in the expansion of the integrals representing the expectation values. | |
| dc.description | 12 pages. Renormalizability properties of the action are clarified and a third-order differential equation for the wave function $Ψ$ with a dependence on the potential $V(Φ)$ is included | |
