论文摘要
借助理论约束，例如扰动单位性和真空稳定性条件以及更新的HIGGS测量的实验数据，并直接搜索LHC处的外来标量，我们对Georgi-Machacek（GM）模型的允许参数空间进行了更新的扫描。借助精制的全局拟合，我们检查了诱导强型一阶电动相变（EWPTS）的允许参数空间，并且仅找到一步相变的现象学上可行。基于结果，我们研究了相关的重力波（GW）信号，并找到大多数可以通过一些建议的实验检测到的大多数。我们还对在不久的将来在LHC的过程中可以作为GM模型有希望的探针进行预测，包括Di-Higgs生产和几个异国情调的标量生产渠道。
With theoretical constraints such as perturbative unitarity and vacuum stability conditions and updated experimental data of Higgs measurements and direct searches for exotic scalars at the LHC, we perform an updated scan of the allowed parameter space of the Georgi-Machacek (GM) model. With the refined global fit, we examine the allowed parameter space for inducing strong first-order electroweak phase transitions (EWPTs) and find only the one-step phase transition is phenomenologically viable. Based upon the result, we study the associated gravitational wave (GW) signals and find most of which can be detected by several proposed experiments. We also make predictions on processes that may serve as promising probes to the GM model in the near future at the LHC, including the di-Higgs productions and several exotic scalar production channels.
