论文摘要
在本文中，我们讨论了一个非觉醒的II型弦真空吸尘器的结构，其宇宙学级别在一个循环级别上，基于Calabi-yau的通用GEPNER模型，在一个循环级别上的构造3倍。我们通过$ z_2 \ times z_4 $对GEPNER模型进行圆柱形，该模型不对称地与某些离散的扭转合并。我们证明，获得的II型弦真空确实导致了一个循环下消失的宇宙常数，而只要假设手性形式，例如'$ q^α_l\ equiv \ equiv \ oint dz j_l^j_l^α（z）$，则不能构造任何时空增压。我们进一步讨论了上述模型的可能概括。
In this article we discuss a construction of non-SUSY type II string vacua with the vanishing cosmological constant at the one loop level based on the generic Gepner models for Calabi-Yau 3-folds. We make an orbifolding of the Gepner models by $Z_2 \times Z_4$, which asymmetrically acts with some discrete torsions incorporated. We demonstrate that the obtained type II string vacua indeed lead to the vanishing cosmological constant at the one loop, whereas any space-time supercharges cannot be constructed as long as assuming the chiral forms such as '$Q^α_L \equiv \oint dz J_L^α(z)$'. We further discuss possible generalizations of the models described above.
