摘要：

我们提出了一种新的机制来产生的电弱标度的框架内的QCD，这是扩展到包括共形不变的标量自由度属于一个更大的不可约表示的$SU(3)_c$。电弱对称性破缺是由1 TeV左右的色标量场凝聚通过希格斯门动态触发的。色玻色子的质量被限制为350 GeV $\lesssim m_S\lesssim $ 3 TeV，其上限由微扰重整化群演化得到.这意味着有色玻色子可以在LHC中产生。如果有色玻色子是带电的，希格斯粒子衰变成两个光子的分支比例可以稍微增加，而且，它可以在未来的线性对撞机上产生。我们的想法，非微扰电子战规模的产生，可以作为一个新的起点，更现实的模型建设，在解决层次问题。

英文摘要：

We propose a new mechanism to generate the electroweak scale within the framework of QCD, which is extended to include conformally invariant scalar degrees of freedom belonging to a larger irreducible representation of $SU(3)_c$. The electroweak symmetry breaking is triggered dynamically via the Higgs portal by the condensation of the colored scalar field around 1 TeV. The mass of the colored boson is restricted to be 350 GeV $\lesssim m_S\lesssim $ 3 TeV, with the upper bound obtained from perturbative renormalization group evolution. This implies that the colored boson can be produced at LHC. If the colored boson is electrically charged, the branching fraction of the Higgs decaying into two photons can slightly increase, and moreover, it can be produced at future linear colliders. Our idea of non-perturbative EW scale generation can serve as a new starting point for more realistic model building in solving the hierarchy problem.
