有效理论的超引力

Supergravity for Effective Theories

Daniel Baumann, Daniel Green

摘要:

高阶导数算子是任何有效场论的核心要素。在超对称理论中,这些算子包括凯勒势中的导数项。我们开发了一个工具包,用于将这种超对称有效场论与超引力耦合。我们解释了如何写最小超引力耦合到手征超场与任意数量的导数和曲率耦合的行动。我们详细讨论了两个例子,显示如何组件的行动同意从线性化描述的Ferrara-Zumino多重峰的期望。在另一篇文章中,我们将形式主义应用于有效通货膨胀理论。

英文摘要:

Higher-derivative operators are central elements of any effective field theory. In supersymmetric theories, these operators include terms with derivatives in the Kähler potential. We develop a toolkit for coupling such supersymmetric effective field theories to supergravity. We explain how to write the action for minimal supergravity coupled to chiral superfields with arbitrary numbers of derivatives and curvature couplings. We discuss two examples in detail, showing how the component actions agree with the expectations from the linearized description in terms of a Ferrara-Zumino multiplet. In a companion paper, we apply the formalism to the effective theory of inflation.
