Yu-Xiao Liu, Li-Jie Zhang, Yi-Shi Duan

摘要:

本文以二维紧致流形$S^2$为额外维,研究了规范和引力背景下的费米子零模。结果是,存在无质量的狄拉克费米子,它具有归一化零模在相当一般的假设下,这些背景上的体积。讨论了球上规范本底的几种特殊情况,得到了几种简单的费米子零模。

英文摘要:

In this letter we study fermionic zero modes in gauge and gravity backgrounds taking a two dimensional compact manifold $S^2$ as extra dimensions. The result is that there exist massless Dirac fermions which have normalizable zero modes under quite general assumptions about these backgrounds on the bulk. Several special cases of gauge background on the sphere are discussed and some simple fermionic zero modes are obtained.
