Calabi-Yau紧化的模约束

Modular Constraints on Calabi-Yau Compactifications

Christoph A. Keller, Hirosi Ooguri

摘要:

我们得到了全局约束的非BPS部门的超对称二维西格玛模型,其目标空间是一个Calabi-Yau流形。当卡-丘三重的总霍奇数足够大时,我们证明了一定存在总共形权小于0.656的非BPS初级态。此外,这样的初级状态的数量至少在总霍奇数中线性增长。我们讨论这些结果的影响,卡-丘几何。

英文摘要:

We derive global constraints on the non-BPS sector of supersymmetric 2d sigma-models whose target space is a Calabi-Yau manifold. When the total Hodge number of the Calabi-Yau threefold is sufficiently large, we show that there must be non-BPS primary states whose total conformal weights are less than 0.656. Moreover, the number of such primary states grows at least linearly in the total Hodge number. We discuss implications of these results for Calabi-Yau geometry.
