标题： Low-Energy Kahler Potentials in Supersymmetric Gauge Theories with (ALMOST) Flat Directions

摘要： 我们推导了超对称规范理论中D平坦方向的超对称低能有效理论。Affleck、Dine和Seiberg的Kähler势通过应用显式保持超对称性的全纯约束来推导。我们还提出了一种简单的方法，用于计算平坦方向流形上各点的Kähler势的所有导数。结合对超势的了解，这些足以完全确定轻度自由度的谱和相互作用。我们在一个手征阿贝尔模型的例子中说明了该方法，并对其在具有动态超对称性破缺的更复杂可计算模型中的应用进行了评论。 显示英文摘要

摘要： We derive the supersymmetric low-energy effective theory of the D-flat directions of a supersymmetric gauge theory. The Kahler potential of Affleck, Dine and Seiberg is derived by applying holomorphic constraints which manifestly maintain supersymmetry. We also present a simple procedure for calculating all derivatives of the Kahler potential at points on the flat direction manifold. Together with knowledge of the superpotential, these are sufficient for a complete determination of the spectrum and the interactions of the light degrees of freedom. We illustrate the method on the example of a chiral abelian model, and comment on its application to more complicated calculable models with dynamical supersymmetry breaking.
