从超几何到纯旋量

From supergeometry to pure spinors

Martin Cederwall

摘要:

在这次演讲中,我们回顾了最大超对称场论(包括超引力)的超空间表述如何自然地导致纯旋量和纯旋量超场的引入,以及为什么形式主义提供了离壳表述。因此,这种纯旋量超场的方法强调场论方面,而不是通常在超弦理论中使用的第一量子化方面。我们讨论了BRST算子是如何产生的,以及动作构造背后的原理,以及一般的Batalin-Vilkovisky框架。D=11的超引力及其最近构造的超对称作用量在整个谈话中被作为一个例子。这是2010年9月在贝尔格莱德举行的第6届数学物理会议上发表的演讲的书面版本。

英文摘要:

In this talk, we review how the superspace formulation of maximally supersymmetric field theories (including supergravity) naturally leads to introduction of pure spinors and pure spinor superfields, and why the formalism provides off-shell formulations. This approach to pure spinor superfields thus stresses field-theoretic aspects rather than the first-quantised ones normally used e.g. in superstring theory. We discuss how the BRST operator arises and the principles behind constructions of actions, as well as the general Batalin-Vilkovisky framework. D=11 supergravity and its recently constructed supersymmetric action are taken as an example throughout the talk. This is the written version of a lecture given at the 6th Mathematical Physics Meeting, Belgrade, September 2010.
