论文摘要
具有Fermonic物质的SP（$ 2N $）仪表理论提供了一个理想的实验室，以建立基于新型复合动力学的标准模型的扩展。示例包括复合希格斯以及顶部的部分综合和复合暗物质。如果没有费米，他们的研究还可以补充基于SU（$ N_C $）量规的理论的研究，它们在大型$ N_C = 2N $限制中共享一个共同行业。我们报告了我们在四维欧几里得晶格中离散的SP（$ 2N $）仪表理论的数值研究的最新进展。特别是，我们在理论中以$ n = 2 $的理论中介绍了介子和嵌合体重的低洼质谱的初步结果。我们还计算了各种$ n $值的拓扑敏感性，将结果推断到大$ n $限制，并讨论Yang-Mills理论中的某些通用属性。
Sp($2N$) gauge theories with fermonic matter provide an ideal laboratory to build extensions of the standard model based on novel composite dynamics. Examples include composite Higgs along with top partial compositeness and composite dark matter. Without fermions, their study also complements those based on SU($N_c$) gauge theories with which they share a common sector in the large $N_c=2N$ limit. We report on our recent progress in the numerical studies of Sp($2N$) gauge theories discretised on a four-dimensional Euclidean lattice. In particular, we present preliminary results for the low-lying mass spectra of mesons and chimera baryons in the theories with $N=2$. We also compute the topological susceptibility for various values of $N$, extrapolate the results to the large $N$ limit, and discuss certain universal properties in Yang-Mills theories.
