D-Brane Wess-Zumino项与U-对偶

D-Brane Wess-Zumino Terms and U-Duality

Eric A. Bergshoeff, Fabio Riccioni

摘要:

我们构造了Wess-Zumino项的规范不变和U-对偶协变表达式,它们对应于任意2<D<11维的一般Dp-膜(对于任意p<D)。这些Wess-Zumino项的一个显着特征是它们包含的标量是10维紧化维数的两倍,与加倍几何一致。我们发现,当D<10时,高维膜的荷都可以表示为0-膜荷的乘积,其中包括D 0-膜荷和NS-NS 0-膜荷。我们给出了这些费用的一般表达式,并展示了它们如何确定一些高维D-膜所属的非平凡共轭类。

英文摘要:

We construct gauge-invariant and U-duality covariant expressions for Wess-Zumino terms corresponding to general Dp-branes (for any p<D) in arbitrary 2<D<11 dimensions. A distinguishing feature of these Wess-Zumino terms is that they contain twice as many scalars as the 10-D compactified dimensions, in line with doubled geometry. We find that for D<10 the charges of the higher-dimensional branes can all be expressed as products of the 0-brane charges, which include the D0-brane and the NS-NS 0-brane charges. We give the general expressions for these charges and show how they determine the non-trivial conjugacy class to which some of the higher-dimensional D-branes belong.
