我们研究了最小步行人工色理论的介子非单线态谱的结构和新出现的特征。在非单态赝标量和矢量通道的精度测量进行比较的期望IR共形场理论和QCD类理论。我们的研究结果有利于一个方案，其中最小的步行人工色是（几乎）共形的红外线，而自发的手征对称性破缺似乎不太合理。
We investigate the structure and the novel emerging features of the mesonic nonsinglet spectrum of the minimal walking technicolor theory. Precision measurements in the nonsinglet pseudoscalar and vector channels are compared to the expectations for an IR-conformal field theory and a QCD-like theory. Our results favor a scenario in which minimal walking technicolor is (almost) conformal in the infrared, while spontaneous chiral symmetry breaking seems less plausible.
