自旋粒子与背景场

Spinning particles and background fields

Eugenia Boffo

AI总结:

本文扩展 N=4 自旋粒子的 BRST 量子化结果,研究如何从该模型导出背景中除度规、Kalb-Ramond 场和伸缩子之外的其他超引力场。

摘要:

通过各自的 sigma 模型,玻色弦和超弦可以与(超)引力场耦合。由于弦的量子化,这些场随后被迫满足其正确的经典运动方程。有迹象表明,具有扩展超对称性的粒子模型可以复制这种行为。超引力的玻色部分包括度规、Kalb-Ramond 2-形式和伸缩子标量场,此前已被证明可由 N=4 自旋粒子的 Becchi-Rouet-Stora-Tyutin 量子化导出。在这些结果的基础上,本文讨论如何找回背景中的其他超引力场。

英文摘要:

Through their respective sigma models, a bosonic string and a superstring can be coupled to (super)gravity fields. These are subsequently forced to satisfy their right classical equation of motions, as a consequence of quantization of the string. There are indications that particle models with extended supersymmetry can replicate this behavior. The bosonic sector of supergravity, comprising the metric, the Kalb-Ramond 2-form and the dilaton scalar field, was already shown to derive from Becchi-Rouet-Stora-Tyutin quantization of the $N=4$ spinning particle. Expanding on these results, here we discuss how to retrieve other Supergravity fields in the background.
