标题： High energy physics and the very-early Universe with LISA

摘要： 引力波实验将在探索宇宙学的前沿和高能下基本场的结构方面发挥关键作用，通过探测或设定早期宇宙中产生的原初引力波背景的强上限。 在这里，我们讨论在低频窗口（$\sim 1 \mu$Hz - 1 Hz）运行的空间激光干涉探测器的影响；我们分析的目的是评估由分数能量密度$\Omega \sim 10^{-16} - 10^{-15}$表征的原初背景的可探测性，这与“慢滚”暴胀模型的预测一致。 显示英文摘要

摘要： Gravitational wave experiments will play a key role in the investigation of the frontiers of cosmology and the structure of fundamental fields at high energies, by detecting, or setting strong upper-limits to, the primordial gravitational wave background produced in the early-Universe. Here we discuss the impact of space-borne laser interferometric detectors operating in the low-frequency window ($\sim 1 \mu$Hz - 1 Hz); the aim of our analysis is to assess the detectability of a primordial background characterized by a fractional energy density $\Omega \sim 10^{-16} - 10^{-15}$, which is consistent with the prediction of "slow-roll" inflationary models.
