We provide, for non-experts, a brief overview of holographic QCD (quantum chromodynamics) and a review of the recent proposal (Hashimoto et al 2010 (arXiv:1003.4988[hep-th])) of a matrix-like description of multi-baryon systems in holographic QCD. Based on the matrix model, we derive the baryon interaction at short distances in multi-flavor holographic QCD. We show that there is a very universal repulsive core of inter-baryon forces for a generic number of flavors. This is consistent with a recent lattice QCD analysis for Nf = 2, 3 where the repulsive core looks universal. We also provide a comparison of our results with the lattice QCD and the operator product expansion analysis.
我们为非专业人士提供了全息 QCD（量子色动力学）的简要概述，并回顾了最近的一项提议（Hashimoto 等人，2010（arXiv：1003.4988[hep-th]）），即在全息 QCD 中对多重子系统进行矩阵式描述。基于矩阵模型，我们推导出多味全息 QCD 中短程的重子相互作用。我们表明，对于任意数量的味道，存在一个非常通用的重子间相互作用的排斥核。这与最近的 Nf=2,3 的格点 QCD 分析一致，其中排斥核看起来是通用的。我们还将我们的结果与格点 QCD 和算子乘积展开分析进行了比较。
