论文摘要
我们探索和对比未来的山脉探测电动相过渡的性质的能力。我们专注于标准模型的真实单重标量表扩展，这是最小，最难以捉摸的框架，可以实现强大的一阶电脉冲相变。通过考虑理论不确定性并在寻找新的标量粒子时采用仪表和希格斯玻色子对之间的强大互补性，我们发现100 TEV质子对撞机有可能确认或伪造强大的一阶过渡。我们的结果暗示，这在其一生中相对较早发生。此外，通过将降低到27 TEV，我们发现较低能源的对撞机也可以探测很大一部分参数空间（如果不是全部）。这样的早期发现将允许在未来的山脉中获得对新现象的精确测量，并将为确定验证这是否确实是标量场的物理残余铺平道路，从而催化了强大的一阶过渡。
We explore and contrast the capabilities of future colliders to probe the nature of the electro-weak phase transition. We focus on the real singlet scalar field extension of the Standard Model, representing the most minimal, yet most elusive, framework that can enable a strong first-order electro-weak phase transition. By taking into account the theoretical uncertainties and employing the powerful complementarity between gauge and Higgs boson pair channels in the searches for new scalar particles, we find that a 100 TeV proton collider has the potential to confirm or falsify a strong first-order transition. Our results hint towards this occurring relatively early in its lifetime. Furthermore, by extrapolating down to 27 TeV, we find that a lower-energy collider may also probe a large fraction of the parameter space, if not all. Such early discoveries would allow for precise measurements of the new phenomena to be obtained at future colliders and would pave the way to definitively verify whether this is indeed the physical remnant of a scalar field that catalyses a strong first-order transition.
