摘要:

手征对称人工色模型成功地调和了电弱精密测试和传统人工色模型之间的紧张关系。在保持传统希格斯机制的前提下,我们着眼于它的最简单的实现,研究了起源于早期宇宙一级相变的原始引力波特征。我们发现,丰富的相变模式产生的物理可行的参数空间。此外,我们还发现了未来实验可能观测到的引力波信号,如LISA、BBO和u-DECIGO。我们的研究结果强调了引力波探测器在探索新的物理补充地面对撞机在多信使天文学时代的重要性。

英文摘要:

A chiral-symmetric technicolor model successfully reconciles the tension between electroweak precision tests and traditional technicolor models. Focusing on its simplest realization preserving the conventional Higgs mechanism, we study its primordial gravitational wave signatures originating from first order phase transitions in the early Universe. We found that abundant phase transition patterns arise from a physically viable parameter space. Besides, we have also found gravitational wave signals possibly visible by future experiments, such as LISA, BBO and u-DECIGO. Our results stress the importance of gravitational wave detectors in exploring new physics complementary to ground colliders in the multi-messenger astronomy era.
