论文摘要
在Twin Higgs模型中，微调的主要来源是获得$ v^2/f^2 $的订单，以获得标准的模型样希格斯，其中$ v $和$ f $分别是electroweak和electroweak和新物理量表。最近提出的Gegenbauer Goldstone模型自然会意识到$ v^2/f^2 \ ll 1 $，因此删除了这种微调来源。通过将两者结合到“ Gegenbauer的双胞胎”中，我们获得了基于对称性的HIGGS部门自然性的模型，与当前的对撞机测量值一致，而无需微调参数。在自然参数空间中，单个耦合偏差为几个百分比的偏差和三位一体的自耦合偏差是不可约合的。因此，尤其是，Gegenbauer双胞胎的指纹首先通过高光度LHC的Di-Higgs测量首先出现。
In Twin Higgs models the dominant source of fine-tuning is the cancellation of order $v^2/f^2$ required to obtain a Standard Model-like Higgs, where $v$ and $f$ are the electroweak and new physics scales, respectively. Recently proposed Gegenbauer Goldstone models naturally realise $v^2/f^2 \ll 1$ and hence remove this source of fine-tuning. By combining the two into `Gegenbauer's Twin', we obtain a symmetry-based model for Higgs sector naturalness consistent with current collider measurements without fine-tuning of parameters. Single-Higgs coupling deviations of a few percent and trilinear self-coupling deviations of order one are irreducible in the natural parameter space. Thus, notably, the fingerprints of Gegenbauer's Twin could emerge first through di-Higgs measurements at the High-Luminosity LHC.
