酉N=2极小超共形场论的完全分类

On the complete classification of the unitary N=2 minimal superconformal field theories

Oliver Gray

摘要:

针对酉N=2极小模型的完全分类(其中时空超对称性的假设已经被丢弃),证明了这样一个理论的配分函数的每个模不变候选确实是极小模型的配分函数.通过对角模型或时空超对称例外模型的轨道折叠构造的模型族证明,对于从Gannon的工作获得的列表中的每一个允许的配分函数,存在酉N=2的极小模型。Kreuzer和Schellekens的猜想,即所有简单的电流不变量都可以作为对角模型的轨道折叠得到,即使在放弃高亏格模不变量的额外假设的情况下,在酉N=2的极小模型的情况下,通过简单的计数论证得到了证实.

英文摘要:

Aiming at a complete classification of unitary N=2 minimal models (where the assumption of space-time supersymmetry has been dropped), it is shown that each modular invariant candidate of a partition function for such a theory is indeed the partition function of a minimal model. A family of models constructed via orbifoldings of either the diagonal model or of the space-time supersymmetric exceptional models demonstrates that there exists a unitary N=2 minimal model for every one of the allowed partition functions in the list obtained from Gannon's work. Kreuzer and Schellekens' conjecture that all simple current invariants can be obtained as orbifolds of the diagonal model, even when the extra assumption of higher-genus modular invariance is dropped, is confirmed in the case of the unitary N=2 minimal models by simple counting arguments.
