我们使用简化的形式重新计算单个引力子环对德西特背景上无质量、共形耦合标量的自质量的贡献，该模型最初由 Boran、Kahya 和 Park 提出 [1-3]。我们的结果解决了 Flob [4] 指出的平坦空间对应极限问题。我们讨论如何在长期项目中使用此计算来消除规范依赖性的线性化有效场方程。
We use a simplified formalism to re-compute the single graviton loop contribution to the self-mass of a massless, conformally coupled scalar on de Sitter background which was originally made by Boran, Kahya and Park [1-3]. Our result resolves the problem with the flat space correspondence limit that was pointed out by Frob [4]. We discuss how this computation will be used in a long-term project to purge the linearized effective field equation of gauge dependence.
