Gianguido Dall'Agata, Fabio Zwirner

AI总结:

本文系统分析了纯五维超引力经Scherk-Schwarz紧化破缺超对称后的单圈有效势,证明其有限性及N=8情形下的负定性,并展望了高维紧化的新研究方向。

摘要:

我们对纯五维超引力在圆上通过Scherk-Schwarz紧化完全破缺超对称后的单圈有效势进行了系统分析,将其视为径向模量的函数。我们讨论了完整紧化理论中的有效势$V_1$与约化理论中的对应量$V_{1,red}$之间的精确对应关系。我们确认,对于任何$N>0$,$V_1$都是有限的,这与$V_{1,red}$形成对比。我们发现,对于破缺的$N=8$超引力,即使在计入Kaluza-Klein态之后,$V_1$也是负定的。我们概述了未来工作的计划,其中研究不同类型的Scherk-Schwarz紧化,仍处于场论层面但至少具有三个额外维度,可能会产生定性上的新结果。

英文摘要:

We perform a systematic analysis of the one-loop effective potential of pure $d=5$ supergravities, with supersymmetry fully broken by a Scherk-Schwarz compactification on the circle, as a function of the radial modulus. We discuss the precise correspondence between the effective potential $V_1$ in the full compactified theory and its counterpart $V_{1,red}$ in the reduced theory. We confirm that $V_1$ is finite for any $N>0$, in contrast to $V_{1,red}$. We find that for broken $N=8$ supergravity $V_1$ is negative definite even after accounting for the Kaluza-Klein states. We outline a program for future work where the study of a different kind of Scherk-Schwarz compactifications, still at the field theory level but with at least three extra dimensions, could lead to qualitatively new results.
