我们建立了一个最小中性自然度模型，在该模型中，顶端伙伴在QCD下不被带电，由于SO(5)/SO(4)的破缺而产生了伪Nambu-Goldstone希格斯模型。色中性的顶端伙伴辐射地产生希格斯势，没有二次发散。电弱标度和整体对称性破缺标度之间的不对准是由于单重态和双重态顶伴贡献的抵消而自然地通过抑制希格斯二次项而得到的。该模型可以嵌入到复合希格斯框架中的紫外全息装置中，甚至实现了有限的希格斯势。
We build a minimal neutral naturalness model in which the top partners are not charged under QCD, with a pseudo Nambu-Goldstone Higgs arising from SO(5)/SO(4) breaking. The color-neutral top partners generate the Higgs potential radiatively without quadratic divergence. The misalignment between the electroweak scale and global symmetry breaking scale is naturally obtained from suppression of the Higgs quadratic term, due to cancellation between singlet and doublet top partner contributions. This model can be embedded into ultraviolet holographic setup in composite Higgs framework, which even realizes finite Higgs potential.
