标题： Alternate Computation of Gravitational Effects from a Single Loop of Inflationary Scalars

摘要： 我们呈现了由质量为零且最小耦合标量的一圈图在de Sitter背景上诱导的重归一化引力子自能的一种新计算方法。 我们的结果考虑到了需要包含宇宙学常数的有限重新归一化，这一点在最初的分析中未被纳入。 我们还避免了关于结构函数的先入为主的观念，而是将结果表达为21个张量微分算符的线性组合。 通过利用我们的结果来量子修正线性化的有效场方程，我们推导出了Weyl张量的电部分（用于引力波）以及两个量化静态点质量引力响应的势的对数修正。 显示英文摘要

摘要： We present a new computation of the renormalized graviton self-energy induced by a loop of massless, minimally coupled scalars on de Sitter background. Our result takes account of the need to include a finite renormalization of the cosmological constant, which was not included in the first analysis. We also avoid preconceptions concerning structure functions and instead express the result as a linear combination of 21 tensor differential operators. By using our result to quantum-correct the linearized effective field equation we derive logarithmic corrections to both the electric components of the Weyl tensor for gravitational radiation and to the two potentials which quantify the gravitational response to a static point mass.
