摘要

我们计算了一般宇宙学背景下无质量费米子环对引力子自能的1环贡献。该结果用于在de Sitter背景下对线性化的爱因斯坦方程进行量子校正，并计算出引力辐射和点质量响应的1环校正。只要德西特相持续存在，重整化群就会被用来对所有阶数求和。

Resumming fermion loops for inflationary gravity

We compute the 1-loop contribution to the graviton self-energy from a loop of massless fermions on a general cosmological background. The result is used to quantum-correct the linearized Einstein equation on de Sitter background and work out 1-loop corrections to gravitational radiation and to the response to a point mass. The renormalization group is employed to sum these to all orders for as long as the de Sitter phase persists.
