论文摘要
我们研究了通货膨胀颗粒含量的小规模标志。我们考虑了通过采用有效的田间理论描述来考虑光旋转2粒子采购原始引力波的情况。在允许螺旋模式的时间相关的声速后,此设置可以通过即将到来的激光干涉仪来检测到蓝色张量光谱。我们的重点是此字段配置随之而来的张量非高斯。在表征CMB尺度下的双光谱振幅和形状功能之后,我们继续前进到较小的尺度上,通过长短模式耦合在张量功率上诱导的各向异性变成(挤压)原始非高斯非高斯。我们在尺度上确定了量表的参数空间生成百分比水平的各向异性,以至于SKA和LISA探索。
We investigate small-scale signatures of the inflationary particle content. We consider the case of a light spin-2 particle sourcing primordial gravitational waves by employing an effective field theory description. Upon allowing time-dependent sound speeds for the helicity modes, this setup delivers a blue tensor spectrum detectable, for example, by upcoming laser interferometers. Our focus is on the tensor non-Gaussianities that ensue from this field configuration. After characterising the bispectrum amplitude and shape-function at CMB scales, we move on to smaller scales where anisotropies induced in the tensor power spectrum by long-short modes coupling become the key handle on (squeezed) primordial non-Gaussianities. We identify the parameter space generating percent level anisotropies at scales soon to be probed by SKA and LISA.
