论文摘要
我们提出了一种吸引人的策略，以同时解释$ W $玻色子质量的CDF II测量并预测可在未来的重力波（GW）实验中可测试的一阶相变（FOPT）的近期测量的标准模型以外的大量方案。我们的分析部署了GW通道和高能量粒子山脉的测量值。我们讨论了这种方法，重点是通过粒子物理的标准模型的扩展提供的特定示例，该粒子物理的扩展包含了附加的标量$ \ mathrm {su}（2）_ {\ rm l} $ triplet耦合到Higgs Boson。我们表明，在这种情况下，强大的Electroweak Fopt自然可以与所测量的$ W $ BOSON质量移位一致。潜在的可观察到的GW签名意味着三重态质量尺度是Tev-ish，始终与$ W $质量异常的价值保持一致。该模型可以在未来的空间干涉仪中进行测试，例如Lisa，Decigo，BBO，Tianqin，Tianqin，Taiji Projects以及未来的Colliders，例如FCC，ILC，CEPC。
We suggest an appealing strategy to probe a large class of scenarios beyond the Standard Model simultaneously explaining the recent CDF II measurement of the $W$ boson mass and predicting first-order phase transitions (FOPT) testable in future gravitational-wave (GW) experiments. Our analysis deploys measurements from the GW channels and high energy particle colliders. We discuss this methodology focusing on the specific example provided by an extension of the Standard Model of particle physics that incorporates an additional scalar $\mathrm{SU}(2)_{\rm L}$ triplet coupled to the Higgs boson. We show that within this scenario a strong electroweak FOPT is naturally realised consistently with the measured $W$ boson mass-shift. Potentially observable GW signatures imply the triplet mass scale to be TeV-ish, consistently with the value preferred by the $W$ mass anomaly. This model can be tested in future space-based interferometers such as LISA, DECIGO, BBO, TianQin, TAIJI projects and in future colliders such as FCC, ILC, CEPC.
