标题： String perturbation theory of Klebanov-Strassler throat

摘要： 在本工作中，我们开发了一个工具，用于研究基于开-闭超弦场论的大半径近似下的Klebanov-Strassler解的弦微扰理论。结合大半径展开和双标度极限，我们发现了一个对应于Klebanov-Strassler解的开-闭超弦场论的微扰背景解。为了说明这种方法的实用性，我们通过在喉咙尖端放置一叠反D3-膜来破坏背景的超对称性。然后，我们找到了大半径近似下三阶的微扰开弦背景解，该解与Kachru-Pearson-Verlinde（KPV）关于反D3-膜超对称性破缺稳定性的著名超引力分析一致。我们找到的开弦场论的微扰背景解预计与NS5-膜探测KS解相对应。 显示英文摘要

摘要： In this work, we develop a tool to study string perturbation theory of the Klebanov-Strassler solution in the large radius approximation based on open-closed superstring field theory. Combining the large radius expansion and a double scaling limit, we find a perturbative background solution of open-closed superstring field theory that corresponds to the Klebanov-Strassler solution. To illustrate the utilities of this approach, we break supersymmetry of the background by placing a stack of anti-D3-branes at the tip of the throat. We then find a perturbative open string background solution to the third order in the large radius approximation, which agrees with the well-known supergravity analysis of Kachru-Pearson-Verlinde (KPV) on the stability of the antiD3-brane supersymmetry breaking. The perturbative background solution to the open string field theory we found is expected to be dual to an NS5-brane probing the KS solution.
