| contents | We examined the quantum properties of scalar-tensor gravity with a coupling to the Gauss-Bonnet term in the low energy limit, exploring both linear and quadratic couplings. We calculated the leading-order corrections to the non-relativistic one-body gravitational potential and the metric by studying the gravitational field of a point-like scalar particle. We studied light-like scattering and compared it with the classical theory. We found that the non-minimal coupling does not contribute to the small-angle scattering for the quadratic coupling but does in the case of linear coupling. The results provide an opportunity to constrain the linear non-minimal coupling to the Gauss-Bonnet term with forthcoming observational data. |
