Sebastiao Mauro, Roberto Balbinot, Alessandro Fabbri, Ilya L. Shapiro

摘要:

本文考虑任意弯曲背景下一般四阶引力场的辅助场公式。的情况下,一个Ricci平坦的背景详细阐述,它表明,有一个等价的标准度量制定。同时,使用辅助场有助于使微扰看起来更简单,结果更清晰。作为应用,我们重新考虑了经典Schwarzschild解的线性扰动。并简要讨论了理论中与大质量非物质鬼效应的关系。

英文摘要:

We consider an auxiliary fields formulation for the general fourth-order gravity on an arbitrary curved background. The case of a Ricci-flat background is elaborated in full details and it is shown that there is an equivalence with the standard metric formulation. At the same time, using auxiliary fields helps to make perturbations to look simpler and the results more clear. As an application we reconsider the linear perturbations for the classical Schwarzschild solution. We also briefly discuss the relation to the effect of massive unphysical ghosts in the theory.
