论文摘要
我们介绍了$ su（4）$量规理论的晶格研究，其中有两个dirac fermions，在两索引反对称表示中有两个，这是一个接近部分整合理论的模型。这项工作的重点是计算频谱计算的方法论和手性点的外推，以多种表示形式进行物质。尽管仍然是技术性的，但这项研究提供了对部分综合理论的非扰动理解的重要步骤，该理论与单占主张理论相比提出了更丰富的动态。首先在扰动理论中研究了多代表性特征，然后通过对晶格数据进行双重前景，通过时间摩托仪相关功能和涂抹光谱密度的联合分析来进行非扰动。
We present a lattice study of the $SU(4)$ gauge theory with two Dirac fermions in the fundamental and two in the two-index antisymmetric representation, a model close to a theory of partial compositeness. Focus of this work are the methodologies behind the computation of the spectrum and the extrapolation of the chiral point for a theory with matter in multiple representations. While being still technical, this study provides important steps towards a non-perturbative understanding of the spectrum of theories of partial compositeness, which present a richer dynamics compared to single-representation theories. The multi-representation features are studied first in perturbation theory, and then non-perturbatively by adopting a dual outlook on lattice data through a joint analysis of time-momentum correlation functions and smeared spectral densities.
