摘要:

本文给出了SU(2)中一个伴随Dirac味的格点研究结果。的光谱,静电势,拓扑电荷,和费米子凝聚的异常尺寸的数据。我们的研究结果被发现是在-符合传统的限制行为,而不是暂时指向一个理论躺在或非常接近的共形窗口的发病,与一个反常的费米凝聚体的尺寸几乎为1。这些发现的影响,强相互作用的动力学模型的建设超出了标准模型进行了讨论。

英文摘要:

We present some results for SU(2) with one adjoint Dirac flavour from lattice studies. Data for the spectroscopy, the static potential, topological charge, and the anomalous dimension of the fermionic condensate are included. Our findings are found to be in- consistent with conventional confining behaviour, instead pointing tentatively towards a theory lying within or very near the onset of the conformal window, with an anomalous dimension of the fermionic condensate of almost 1. Implications of these findings on the building of models of strongly-interacting dynamics beyond the standard model are discussed.
