轻复合希格斯粒子的最小实现
Toward the minimal realization of a light composite Higgs
摘要：
正在进行的工作是报告一个特别有趣的规范理论与费米子二重态的双指数对称（六重态）表示的SU（3）色规范群。扩展以前的研究，我们概述了我们的战略，因为我们调查戈德斯通动力学和电弱标度设置从手征对称性破缺（$χ$ SB），从狄拉克算子和相关的手征凝聚体的谱测试GMOR关系，开始开发和测试$χ$ SB的基于混合作用的改进分析，并在固定拓扑下制定新的运行计划，以从p-状态跨越到p-状态，在$χ$ SB体系中，继续研究光$0^{++}$标量及其与声子的关系，探索从微扰UV标度到手征对称性破缺标度的标度依赖运行耦合。我们的观察表明，该模型非常接近共形窗口，一个轻的复合标量，也许是希格斯冒名顶替者，无论是否有类似于狄克逊的解释，似乎都以$0^{++}$量子数出现。在3 TeV尺度上，模型中最轻的重子具有有趣的意义。
英文摘要：
Work in progress is reported on a particularly interesting gauge theory with a fermion doublet in the two-index symmetric (sextet) representation of the SU(3) color gauge group. Extending previous studies we outline our strategy as we investigate Goldstone dynamics and Electroweak scale setting from chiral symmetry breaking ($χ$ SB), test the GMOR relation from the spectrum of the Dirac operator and the related chiral condensate, begin to develop and test mixed action based improved analysis of $χ$ SB with new run plans at fixed topology to cross over from the p-regime to the epsilon-regime of $χ$ SB, continue to pursue the light $0^{++}$ scalar and its relation to the dilaton, and probe the scale-dependent running coupling from the perturbative UV scale to the scale of chiral symmetry breaking. Our observations suggest that the model is very close to the conformal window and a light composite scalar, perhaps the Higgs impostor with or without dilaton-like interpretation, appears to emerge with $0^{++}$ quantum numbers. The lightest baryon of the model on the 3 TeV scale has intriguing implications.
