论文摘要
我们研究了通货膨胀过程中产生的重力波的原始随机背景的1循环。在单个锁定中，在慢速滚动的领先顺序中，量子校正保持幅度不含尺度，当对称破裂的模式不同时，这并非如此。特别是，当在通货膨胀期间与固体通货膨胀一样，当空间差异也破裂时，会产生外部动量中的对数。我们将日志跑的外观与扩张不变性的自发破坏有关。在将来的高灵敏度CMB极化和GWS实验中，该运行可能对将单锁与通货膨胀的替代模型区分开来是有用的。
We study 1-loop corrections to the primordial stochastic background of gravitational waves produced during inflation. While in single-clock, at the leading order in slow-roll, quantum corrections keep the amplitude scale-free this is not the case when the pattern of symmetry breaking is different. In particular, when spatial diffeomorphisms are also broken during inflation as for solid inflation, a log-running in the external momentum is generated. We relate the appearance of a log-running to the spontaneous breaking of dilatation invariance. The running could be instrumental to distinguish single-clock from alternative models of inflation in future high sensitivity CMB polarisation and GWs experiments.
