无引力的超引力及其BV表述

Supergravity without gravity and its BV formulation

Julian Kupka, Charles Strickland-Constable, Fridrich Valach

AI总结:

本文研究十维超引力在广义几何表述下的一个简单极限,得到仅含伸缩子与伸缩微子的理论,并利用其几何简单性构建了费米子变量所有阶的完整BV扩展。

摘要:

十维超引力的广义几何表述提示了一个特别简单的“极限”,由此得到一个仅以伸缩子和伸缩微子为动力学自由度的理论。该理论仍然在广义微分同胚和局域超对称下保持不变,并且在许多方面与原始超引力在结构上相似,这使其成为理解完整物理框架中更微妙方面的便捷试验场。特别是,伸缩子理论的简单性和几何性质使我们能够构建一个在费米子变量上到所有阶的完整BV扩展。

英文摘要:

The generalised-geometric formulation of 10-dimensional supergravity suggests a particular simple "limit", which results in a theory whose only dynamical degrees of freedom are the dilaton and the dilatino. The theory is still invariant both under generalised diffeomorphisms and a local supersymmetry and in many aspects is structurally similar to the original supergravity, which makes it a convenient playground for understanding more subtle aspects of the full physical setup. In particular, the simplicity and the geometric nature of the dilatonic theory allow us to build a full BV extension to all orders in the fermionic variables.
