D7-anti-D7双层膜：全息动力学对称性破缺
D7-anti-D7 bilayer: holographic dynamical symmetry breaking
摘要：
我们考虑了一个2+1维动力学对称破缺的全息模型，其中一个平行的D 7-反D 7膜对融合成一个单一的物体，对应于U（1）XU（1）->U（1）对称破缺模式。我们表明，电流-电流的关联函数可以计算分析和表现出低动量结构时，预计全球对称性自发打破。我们还发现，这些关联函数的极点归因于无限塔的矢量介子具有等间距的质量。
英文摘要：
We consider a holographic model of dynamical symmetry breaking in 2+1-dimenisons, where a parallel D7-anti-D7 brane pair fuse into a single object, corresponding to the U(1)XU(1)->U(1) symmetry breaking pattern. We show that the current-current correlation functions can be computed analytically and exhibit the low momentum structure that is expected when global symmetries are spontaneously broken. We also find that these correlation functions have poles attributable to infinite towers of vector mesons with equally spaced masses.
