超陪集模型中的N=2超共形对称性

N=2 Superconformal Symmetry in Super Coset Models

Thomas Creutzig, Peter B. Ronne, Volker Schomerus

摘要:

我们将具有N=(2,2)世界片超对称性的模型的Kazama-Suzuki构造推广到了超群的陪集S/K.在允许扩张到N=2超共形代数的容许目标空间中,有一些单李超群,包括PSL(N| N)。本文以GL(1)上的N=1 WZNW模型为例进行了分析|1)。在构造了它的N=2超共形代数后,我们确定了该理论的手征环(反手征环).它表现出一个有趣的世界片和目标空间超对称性之间的相互作用。

英文摘要:

We extend the Kazama-Suzuki construction of models with N=(2,2) world-sheet supersymmetry to cosets S/K of supergroups. Among the admissible target spaces that allow for an extension to N=2 superconformal algebras are some simple Lie supergroups, including PSL(N|N). Our general analysis is illustrated at the example of the N=1 WZNW model on GL(1|1). After constructing its N=2 superconformal algebra we determine the (anti-)chiral ring of the theory. It exhibits an interesting interplay between world-sheet and target space supersymmetry.
