We present a novel realization of a composite Higgs, which can naturally produce top partners above the current LHC bounds without increasing the tuning above 10%. The essential ingredients are softened breaking of the Higgs shift symmetry as well as maximal symmetry, which turn out to perfectly complement each other. The 5D realization of this model is particularly simple: universal UV and IR boundary conditions for the bulk fermions containing the SM fields will cure the problems of existing holographic composite Higgs models and provide a complete viable model for a naturally light Higgs without much tuning.

通过通用边界条件的自然复合希格斯粒子

我们提出了复合希格斯粒子的新实现，它可以自然地产生高于当前 LHC 界限的顶级伙伴，而无需将调谐增加 10% 以上。基本成分是希格斯位移对称性和最大对称性的软化破坏，结果证明它们完美地相互补充。这个模型的 5D 实现特别简单：包含 SM 场的体费米子的通用 UV 和 IR 边界条件将解决现有全息复合希格斯模型的问题，并为自然光希格斯提供一个完整可行的模型，无需太多调整。
