一个轻的希格斯冒充者能隐藏在复合规范模型中吗？
Can a light Higgs impostor hide in composite gauge models?
摘要：
研究了SU（3）色规范群的双指数对称（六重态）表象中含有费米子味偶态的强相互作用规范理论。在以前的研究中，手征凝聚体和质谱被证明是一致的手征对称性破缺（$χ$ SB）在消失的费米子质量。最近报道的$β$ -函数与这一观察结果并不矛盾，这表明该模型非常接近共形窗口，并且轻的“希格斯冒名顶替者”可以作为复合态出现。在这项工作中，我们描述的方法和初步结果研究的出现轻复合标量与$0^{++}$量子数。
英文摘要：
The frequently discussed strongly interacting gauge theory with a fermion flavor doublet in the two-index symmetric (sextet) representation of the SU(3) color gauge group is investigated. In previous studies the chiral condensate and the mass spectrum were shown to be consistent with chiral symmetry breaking ($χ$SB) at vanishing fermion mass. The recently reported $β$-function is not inconsistent with this observation, suggesting that the model is very close to the conformal window and a light "Higgs impostor" could emerge as a composite state. In this work we describe the methodology and preliminary results of studying the emergence of the light composite scalar with $0^{++}$ quantum numbers.
