天空中标准模型的印记:暴胀后希格斯粒子衰变产生的引力波

Imprints of the Standard Model in the Sky: Gravitational Waves from the decay of the Higgs after inflation

Daniel G. Figueroa

摘要:

标准模型(SM)希格斯粒子的存在意味着在暴胀结束后不久,希格斯粒子的衰变产物会产生引力波(GW)背景。理论上,SM的所有Yukawa和$SU(2)_L$规范耦合都是GW谱的特征。在实践中,来自最强耦合物种的信号占主导地位,使得其他物种的信息不可访问。如果被探测到,这种背景可以用于测量高能粒子物理学的性质,包括超越SM。为了实现这一目标,需要新的高频GW检测技术,超越目前计划的检测器。

英文摘要:

The existence of the Standard Model (SM) Higgs implies that a gravitational wave (GW) background is generated by the decay products of the Higgs, soon after the end of inflation. Theoretically, all Yukawa and $SU(2)_L$ gauge couplings of the SM are imprinted as features in the GW spectrum. In practice, the signal from the most strongly coupled species dominates, rendering inaccesible the information on the other species. If detected, this background could be used for measuring properties of high-energy particle physics, including beyond the SM. To achieve this goal, new high frequency GW detection technology is required, beyond that of currently planned detectors.
