双D-膜的双场论

Double Field Theory for Double D-branes

Cecilia Albertsson, Shou-Huang Dai, Pei-Wen Kao, Feng-Li Lin

摘要:

我们考虑了平坦空间中D-膜上开弦的Hull二重形式,并构造了相应的有效二重场论。我们证明了双重形式主义的世界面边界条件以统一的方式描述了一对T-对偶D-膜,我们称之为双重D-膜。我们计算了边界规范耦合的单圈β函数,从而得到了双D膜的有效场论。有效场论用双场的DBI作用量来描述。这个DBI作用量的T-对偶协变形式因此是一种“主”作用量,它描述了所有由T-对偶变换相关的双D-膜构型。我们讨论了这个有效的理论的一些方面。

英文摘要:

We consider Hull's doubled formalism for open strings on D-branes in flat space and construct the corresponding effective double field theory. We show that the worldsheet boundary conditions of the doubled formalism describe in a unified way a T-dual pair of D-branes, which we call double D-branes. We evaluate the one-loop beta function for the boundary gauge coupling and then obtain the effective field theory for the double D-branes. The effective field theory is described by a DBI action of double fields. The T-duality covariant form of this DBI action is thus a kind of "master" action, which describes all the double D-brane configurations related by T-duality transformations. We discuss a number of aspects of this effective theory.
