LIGO作为黑暗扇区的探测器

LIGO as a probe of Dark Sectors

Fei Huang, Veronica Sanz, Jing Shu, Xiao Xue

摘要:

我们展示了当前的LIGO数据如何能够探测标准模型之外的有趣理论,特别是暗区,其中暗希格斯粒子通过一阶相变触发对称破缺。我们使用公开的LIGO O2数据来说明这些部门,即使与标准模型断开连接,也可以通过引力波探测器探测。我们将LIGO测量与暗区的模型内容和质量尺度联系起来,发现当前的O2数据正在测试一系列广泛的场景,其中$SU(N)$理论与$N_f$费米子的突破是由$Λ\simeq 10^8 - 10^9$ GeV尺度的暗希格斯粒子触发的,其标量势具有合理的参数。

英文摘要:

We show how current LIGO data is able to probe interesting theories beyond the Standard Model, particularly Dark Sectors where a Dark Higgs triggers symmetry breaking via a first-order phase transition. We use publicly available LIGO O2 data to illustrate how these sectors, even if disconnected from the Standard Model, can be probed by Gravitational Wave detectors. We link the LIGO measurements with the model content and mass scale of the Dark Sector, finding that current O2 data is testing a broad set of scenarios where the breaking of $SU(N)$ theories with $N_f$ fermions is triggered by a Dark Higgs at scales $Λ\simeq 10^8 - 10^9$ GeV with reasonable parameters for the scalar potential.
