论文摘要
我们使用QCD的全息偶双重双重态分析了激发的baryon状态，该态是根据相交的D4/D8-Brane系统定义的。在五维弯曲时空中，对这些模型中的重子研究的研究是对它们的拓扑理论的拓扑。但是，这允许人们仅获得一定类别的重子。我们试图提出一个框架，以便可以系统地对待一组激动人心的重子。这是通过采用Witten的原始想法来实现的，该想法指出，BARYON由由Baryon Vertex发出的$ N_C $打开字符串组成的系统描述。我们认为，该系统可以通过桥本 - iizuka-yi的ADHM型矩阵模型以及开放式巨大模式的无限塔配制。使用此设置，我们可以确定激发重子的光谱，并将它们与实验数据进行比较。特别是，我们推导了一个核子regge轨迹的公式，假设位于轨迹的激发核子的特征是刺激了baryon顶点上的单个开放式弦。
We analyze excited baryon states using a holographic dual of QCD that is defined on the basis of an intersecting D4/D8-brane system. Studies of baryons in this model have been made by regarding them as a topological soliton of a gauge theory on a five-dimensional curved spacetime. However, this allows one to obtain only a certain class of baryons. We attempt to present a framework such that a whole set of excited baryons can be treated in a systematic way. This is achieved by employing the original idea of Witten, which states that a baryon is described by a system composed of $N_c$ open strings emanating from a baryon vertex. We argue that this system can be formulated by an ADHM-type matrix model of Hashimoto-Iizuka-Yi together with an infinite tower of the open string massive modes. Using this setup, we work out the spectra of excited baryons and compare them with the experimental data. In particular, we derive a formula of the nucleon Regge trajectory assuming that the excited nucleons lying the trajectory are characterized by the excitation of a single open string attached on the baryon vertex.
