论文摘要
我们将``宇宙对撞机''的覆盖率从CMB量表到干涉仪量表的通货膨胀期间进行``宇宙对撞机''的范围。考虑到仪表玻色子和伪尺度发气量之间的Chern-Simons耦合，横向计模式之一是有效产生的，其反向衰减在原始标量和张量扰动中留下了烙印。我们研究了这些扰动的相关函数，并从CMB可观察物中得出了对参数空间的更新约束。然后，我们将张量功率谱推断到较小的尺度，并考虑到量规场对通货膨胀动力学的影响。我们的结果表明，可以从包含整个电流和计划的干涉仪范围的特征引力波信号中检测到通货膨胀期间的大量量规场的存在。
We extend the reach of the ``cosmological collider'' for massive gauge boson production during inflation from the CMB scales to the interferometer scales. Considering a Chern-Simons coupling between the gauge bosons and the pseudoscalar inflaton, one of the transverse gauge modes is efficiently produced and its inverse decay leaves an imprint in the primordial scalar and tensor perturbations. We study the correlation functions of these perturbations and derive the updated constraints on the parameter space from CMB observables. We then extrapolate the tensor power spectrum to smaller scales consistently taking into account the impact of the gauge field on inflationary dynamics. Our results show that the presence of massive gauge fields during inflation can be detected from characteristic gravitational wave signals encompassing the whole range of current and planned interferometers.
