六维超引力的N=1超场描述

N=1 superfield description of six-dimensional supergravity

Hiroyuki Abe, Yutaka Sakamura, Yusuke Yamada

摘要:

我们用四维N=1的超场来表示六维超引力的作用,着重于作用的模依赖性。张量-矢量扇区中作用量的规范不变性是以非常重要的方式实现的,它决定了作用量的模依赖性。由此产生的模量依赖是复杂的,特别是对形状模量。我们的结果是减少到已知的超场作用的六维整体超对称理论和五维超引力通过替换模超场的背景值和通过执行降维,分别。

英文摘要:

We express the action of six-dimensional supergravity in terms of four-dimensional N=1 superfields, focusing on the moduli dependence of the action. The gauge invariance of the action in the tensor-vector sector is realized in a quite nontrivial manner, and it determines the moduli dependence of the action. The resultant moduli dependence is intricate, especially on the shape modulus. Our result is reduced to the known superfield actions of six-dimensional global SUSY theories and of five-dimensional supergravity by replacing the moduli superfields with their background values and by performing the dimensional reduction, respectively.
