随机暴胀标量电动力学

Stochastic Inflationary Scalar Electrodynamics

T. Prokopec, N. C. Tsamis, R. P. Woodard

摘要:

我们在de Sitter背景下随机地建立了标量量子电动力学理论。这再现了每个循环顺序的主要红外光谱。它还允许一个求和的一系列领先的红外光谱,以获得明确的,非微扰的结果,后期的时间行为的系统。结果之一是证实了戴维斯、迪莫普洛斯、普罗克维和托恩奎斯特的猜想,即超视界光子在暴胀过程中获得质量。我们计算出光子的质量约为3.2991 H^2。标量保持微扰轻态,质量平方约为0.8961 3 e^2 H^2/8pi^2。有趣的是,诱导的宇宙学常数变化是负的,约为-0.6551 3 G H^4/pi。

英文摘要:

We stochastically formulate the theory of scalar quantum electrodynamics on a de Sitter background. This reproduces the leading infrared logarithms at each loop order. It also allows one to sum the series of leading infrared logarithms to obtain explicit, nonperturbative results about the late time behavior of the system. One consequence is confirmation of the conjecture by Davis, Dimopoulos, Prokopec and Tornkvist that super-horizon photons acquire mass during inflation. We compute a photon mass-suqared of about 3.2991 H^2. The scalar stays perturbatively light with a mass-squared of about 0.8961 3 e^2 H^2/8pi^2. Interestingly, the induced change in the cosmological constant is negative, of about -0.6551 3 G H^4/pi.
