磁化环面上(4+2n)维SYM理论及其混合的超场描述

Superfield description of (4+2n)-dimensional SYM theories and their mixtures on magnetized tori

Hiroyuki Abe, Tomoharu Horie, Keigo Sumita

摘要:

本文对二维超对称Yang-Mills(SYM)理论($(4+2n)$)及其混合物进行了系统的降维处理,并在二维环面上对它们进行了紧致化处理,使其在原有SYM理论的全${\mathcal N}=2,3$或$4$中保留了部分${\mathcal N}=1$超对称性.它是在一个$\mathcal N=1$超空间中表达的,该超空间考虑了超对称性的不破缺,而四维有效作用量则用表示$\mathcal N=1$矢量和手征多重态的超场来表示,这些超场来自于高维SYM理论.我们还确定了物质凯勒度量和超势耦合以及规范动力学函数的有效作用的依赖性和几何模量。这些结果对于用SYM理论或D-膜包裹磁化环面,特别是它们具有不同维数的混合构型的各种唯象/宇宙学模型的建立将是有用的。

英文摘要:

We provide a systematic way of dimensional reduction for $(4+2n)$-dimensional $U(N)$ supersymmetric Yang-Mills (SYM) theories ($n=0,1,2,3$) and their mixtures compactified on two-dimensional tori with background magnetic fluxes, which preserve a partial ${\mathcal N}=1$ supersymmetry out of full ${\mathcal N}=2,3$ or $4$ in the original SYM theories. It is formulated in an $\mathcal N=1$ superspace respecting the unbroken supersymmetry, and the four-dimensional effective action is written in terms of superfields representing $\mathcal N=1$ vector and chiral multiplets, those arise from the higher-dimensional SYM theories. We also identify the dilaton and geometric moduli dependence of matter Kähler metrics and superpotential couplings as well as of gauge kinetic functions in the effective action. The results would be useful for various phenomenological/cosmological model buildings with SYM theories or D-branes wrapping magnetized tori, especially, with mixture configurations of them with different dimensionalities from each other.
