F-理论中不破缺对称性的度量

Gauging Unbroken Symmetries in F-theory

Chia-Yi Ju, Warren Siegel

摘要:

F理论试图明显地包含所有的U对偶性。与它的T-对偶显式伙伴基于弦流代数不同,F-理论基于高维膜流代数。像T-对偶显性理论一样,它具有$O(D-1,1)^2$不破缺的对称性,F-理论真空也具有某些对称性(“$H$“)。它的一个重要而奇特的性质是世界体积指数也是时空指数。这使得整体膜电流代数与$H$对称电流不相容。解决方案是引入世界体积协变导数,它依赖于$H$坐标,即使在“平坦”的背景。我们还将给出5-膜的情况作为一个明确的例子。

英文摘要:

F-theory attempts to include all U-dualities manifestly. Unlike its T-dual manifest partner, which is based on string current algebra, F-theory is based on higher dimensional brane current algebra. Like the T-dual manifest theory, which has $O(D-1,1)^2$ unbroken symmetry, the F-theory vacuum also enjoys certain symmetries ("$H$"). One of its important and exotic properties is that worldvolume indices are also spacetime indices. This makes the global brane current algebra incompatible with $H$ symmetry currents. The solution is to introduce worldvolume covariant derivatives, which depend on the $H$ coordinates even in a "flat" background. We will also give as an explicit example the 5-brane case.
