强翘曲下的D3-brane动力学

On D3-brane Dynamics at Strong Warping

Heng-Yu Chen, Yu Nakayama, Gary Shiu

摘要:

我们使用arXiv:0805.3700 [hep-th]中讨论的哈密顿公式研究了一般IIB翘曲紧化中D3膜的动力学。考虑到闭弦和开弦的涨落,我们导出了支配探测D3膜运动的弯曲Kahler势。通过引入D3的反作用,我们还讨论了如何解决在翘曲背景下的D 7膜上定义全纯规范耦合的问题。

英文摘要:

We study the dynamics of a D3 brane in generic IIB warped compactifications, using the Hamiltonian formulation discussed in arXiv:0805.3700 [hep-th]. Taking into account of both closed and open string fluctuations, we derive the warped Kahler potential governing the motion of a probe D3 brane. By including the backreaction of D3, we also comment on how the problem of defining a holomorphic gauge coupling on wrapped D7 branes in warped background can be resolved.
