论文摘要
我们得出了标量 - 高斯河网理论的弱场极限,并使用基于空间的实验将新颖的界限放在参数空间上。为了在各种实验的背景下分析该理论,我们计算出具有平面,圆柱形和球形对称性的源质量周围的爱因斯坦重力的偏差。我们发现围绕球形和圆柱源的牛顿电位的校正可能大于PPN校正,足够接近源。我们使用它来改善对标量 - 高斯 - 邦网耦合参数$λ$的实验室限制,将其通过两个数量级。此处报告的当前实验室和太阳系界限被从黑洞衍生而来的测试所取代。
We derive the weak field limit of scalar-Gauss-Bonnet theory and place novel bounds on the parameter space using terrestrial and space-based experiments. In order to analyze the theory in the context of a wide range of experiments, we compute the deviations from Einstein gravity around source masses with planar, cylindrical, and spherical symmetry. We find a correction to the Newtonian potential around spherical and cylindrical sources that can be larger than PPN corrections sufficiently close to the source. We use this to improve on laboratory constraints on the scalar-Gauss-Bonnet coupling parameter $Λ$ by two orders of magnitude. Present laboratory and Solar System bounds reported here are superseded by tests deriving from black holes.
