畴壁AdS/QCD

Domain Wall AdS/QCD

Nick Evans, Jack Mitchell

摘要:

利用畴壁费米子构造了一种新的QCD全息描述。该结构由D5膜几何中的探测D 7膜组成,描述了5+1d规范理论中4+1d缺陷上的夸克。然后,我们紧化一维的D5引入限制的规范自由度。此外,我们允许一个空间依赖的质量项的D 7膜夸克孤立手征费米子3+1d域壁。D 7世界体积场,当限制在畴壁位置时,提供AdS/QCD描述。我们计算光谱并与数据进行比较。我们包括更高的维度运营商系统地改善描述。

英文摘要:

We construct a new holographic description of QCD using domain wall fermions. The construction consists of probe D7 branes in a D5 brane geometry describing quarks on a 4+1d defect in a 5+1d gauge theory. We then compactify one dimension of the D5 to introduce confinement in the gauge degrees of freedom. In addition we allow a spatial dependent mass term for the D7 brane quarks to isolate chiral fermions on 3+1d domain walls. The D7 world volume fields, when restricted to the domain wall position, provide an AdS/QCD description. We compute the spectrum and compare to data. We include higher dimension operators to systematically improve the description.
