AI总结:

本文研究非超对称II型扭折对称破缺模型,通过每个扭折因子中保留超荷算子实现真空能消除,分类了有限阿贝尔点群下的扭折结构,探讨了更高环的可能持续性。

摘要:

我们系统研究了非超对称II型扭折扭折对称破缺模型,其在弦扰论中一环真空能为零。这些模型通过在每个扭折因子中保留超荷算子实现,尽管整体空间时间超对称被显式破坏。我们完整分类了此类扭折结构,仅允许有限阿贝尔点群$\mathbb{Z}_k \times \mathbb{Z}_k$,其中$k=2,3,4$。我们提供了详细构造,以及具有非阿贝尔点群的其他例子。对于某些模型,这种抵消可能在更高环中持续。

英文摘要:

We present a systematic study of non-supersymmetric type II toroidal asymmetric orbifolds with vanishing vacuum energy at one-loop in string perturbation theory. These are engineered through the conservation of a supercharge-like operator in each individual sector in the orbifold sum, despite the overall explicit breaking of spacetime SUSY. We provide a full classification of such orbifolds with finite Abelian point-group, which can only admit $\mathbb{Z}_k \times \mathbb{Z}_k$ point group with $k=2,3,4$. We present detailed constructions, alongside other examples with non-Abelian point group. For some of these models, it is possible that this cancellation persists at higher loops.
