论文摘要
我们对使用$（5）\ so（4）$全局对称性破坏模式的4D最小复合希格斯模型的描述进行了重新评估。在QCD背景下，特定的5D自下而上全息治疗受到先前工作的启发，它可以研究旋转和旋转零共振。最终的频谱由在不间断的$（4）$子组下进行转换的州以及$（5）/so（4）$ coset中的量子数字的国家组成。旋转一个状态以线性径向轨迹排列，而破碎的亚组的状态通常较重。来自coset空间的旋转零状态对应于4D中的四个无质量的金石玻色子。其中一个扮演了希格斯玻色子的角色。然后实施从实验限制（Higgs耦合，$ S $参数等）中得出的限制，我们得出结论，该模型能够在不遇到现象学困难的情况下适应新的矢量谐振，范围为$ 2 $ tev至$ 3 $ tev。还估计了在SM量规玻色散射过程中控制这些新状态的生产的耦合。该方法可以扩展到其他破坏模式。
We reassess employing the holographic technique to the description of 4D minimal composite Higgs model with $SO(5)\to SO(4)$ global symmetry breaking pattern. The particular 5D bottom-up holographic treatment is inspired by previous work in the context of QCD and it allows to study spin one and spin zero resonances. The resulting spectrum consists of the states transforming under the unbroken $SO(4)$ subgroup and those with quantum numbers in the $SO(5)/SO(4)$ coset. The spin one states are arranged in linear radial trajectories, and the states from the broken subgroup are generally heavier. The spin zero states from the coset space correspond to the four massless Goldstone bosons in 4D. One of them takes the role of the Higgs boson. Restrictions derived from the experimental constraints (Higgs couplings, $S$ parameter, etc.) are then implemented and we conclude that the model is able to accommodate new vector resonances with masses in the range $2$ TeV to $3$ TeV without encountering phenomenological difficulties. The couplings governing the production of these new states in the processes of the SM gauge boson scattering are also estimated. The method can be extended to other breaking patterns.
