Min-Young Choi, Kyung Kiu Kim, Choonkyu Lee, Ki-Myeong Lee

摘要:

本文研究了自发破缺的(4+1)维Yang-Mills理论中双子瞬子的Higgs场组态。在一般非正则基下构造了ADHM瞬子背景下协变Laplace方程的伴随标量场解,并利用它们研究了当规范场取Jackiw-Nohl-Rebbi瞬子解时,双子瞬子的Higgs场组态.对于这些对应于小瞬子数的解,我们详细地考虑了希格斯场的零轨迹,它描述了弦论中连接平行D4-膜的超管的截面。利用Higgs零点的信息讨论了Jackiw-Nohl-Rebbi解的剩余规范自由度。

英文摘要:

We study Higgs field configurations of dyonic instantons in spontaneously broken (4+1)-dimensional Yang-Mills theory. The adjoint scalar field solutions to the covariant Laplace equation in the ADHM instanton background are constructed in general noncanonical basis, and they are used to study explicitly the Higgs field configurations of dyonic instantons when the gauge fields are taken by Jackiw-Nohl-Rebbi instanton solutions. For these solutions corresponding to small instanton number we then consider in some detail the zero locus of the Higgs field, which describes the cross section of supertubes connecting parallel D4-branes in string theory. Also the information on the Higgs zeroes is used to discuss the residual gauge freedom concerning the Jackiw-Nohl-Rebbi solutions.
