论文摘要
宇宙对撞机在通货膨胀期间提供了粒子物理的独立探针。我们通过重力波（GW）探针将宇宙撞机物理学的研究扩展到较小的尺度。使用Chern-Simons相互作用，大规模的载体场可以获得化学势，其颗粒产生会引起明显的非高斯GW信号。我们计算诱导的GW 3点相关函数的质量和自旋依赖性在挤压极限中，并估计其幅度。在电流和即将到来的GW干涉仪实验中可以检测到此类信号。
The cosmological collider provides a model-independent probe of particle physics during inflation. We extend the study of cosmological collider physics to much smaller scales through gravitational wave (GW) probes. With a Chern-Simons interaction, a massive vector field can obtain a chemical potential and its particle production can cause significant non-Gaussian GW signals. We calculate the mass and spin dependences of the induced GW 3-point correlation function in the squeezed limit, and estimate its amplitude. Such signals may be detectable in the current and upcoming GW interferometer experiments.
