论文摘要
在描述高能的重力时，自然会在曲率上引入二次术语作为对爱因斯坦 - 希尔伯特作用的首次校正。在量子动机$ r+r^2+c^{μνρσ} c_ {μνρσ} $理论的情况下，研究了静态的，球体对称的经典解。与一般相对论的情况相反，该指标被迫成为施瓦茨柴尔德一号，而已经发现了具有不同引力电位的大量溶液。它显示了这些解决方案如何填充理论的参数空间，并讨论了这种修改潜能的某些现象学含义。
When describing gravity at high energies it is natural to introduce terms quadratic in the curvature as first corrections to the Einstein-Hilbert action. Static, spherically symmetric classical solutions are studied in the case of the quantum-motivated $R+R^2+C^{μνρσ}C_{μνρσ}$ theory. In contrast with the case of General Relativity, where the metric is forced to be the Schwarzschild one, a large spectrum of solutions with different gravitational potentials has been found. It is shown how these solutions populate the parameter space of the theory, and some possible phenomenological implications of this modified potential are discussed.
