大C场背景下D4-brane上的超对称性和BPS态

Supersymmetry and BPS States on D4-brane in Large C-field Background

Chen-Te Ma, Chi-Hsien Yeh

摘要:

在本文中,我们继续了在大C场背景下D4-膜低能有效理论的研究。有效作用的规范场部分在早期的工作中被发现。在本文中,我们重点讨论了物质场部分的作用量和超对称变换。此外,我们还计算了超代数的中心荷,并广泛地研究了这一有效理论的BPS解。本文考虑的BPS态包括类光规范场组态、终止于D4解的F1、倾斜的D4-膜、具有两种磁荷(D2终止于D4)的BPS解、D4-膜的全纯嵌入以及两个D4-膜沿2-膜的相交。

英文摘要:

In this paper, we continue our previous study of the low energy effective theory for D4-brane in the large C-field background. The gauge field part of the effective action was found in an earlier work. In this paper, we focus on the matter field part of the action and the supersymmetry transformation. Moreover, we calculate the central charges of super algebra and extensively study BPS solutions of this effective theory. The BPS states considered in this paper include light-like gauge field configurations, the F1 ending on D4 solution, tilted D4-brane, BPS solution with two types of magnetic charges (D2 ending on D4), holomorphic embedding of D4-brane and the intersection of two D4-branes along a 2-brane.
