An attractive mechanism to break supersymmetry in vacua with zero vacuum energy arose in E(8) x E(8) heterotic models with hidden sector gaugino condensate. An H flux balances the exponentially small condensate on shell and fixes the complex structure moduli. At quantum level this balancing is, however, obstructed by the quantization of the H flux. We show that the warped flux compactification background in heterotic M theory can solve this problem through a warp-factor suppression of the integer flux relative to the condensate. We discuss the suppression mechanism both in the M theory and the four-dimensional effective theory and provide a derivation of the condensate's superpotential which is free of delta-function squared ambiguities.
在具有隐藏区规范微子凝聚的E(8)×E(8)杂化模型中，出现了一种在零真空能量的真空中打破超对称的诱人机制。一个H通量平衡了壳上指数级小的凝聚，并固定了复结构模量。然而，在量子水平上，这种平衡受到H通量量子化的阻碍。我们表明，杂化M理论中的弯曲通量紧致化背景可以通过相对于凝聚对整数通量的弯曲因子抑制来解决这个问题。我们在M理论和四维有效理论中都讨论了抑制机制，并给出了一个没有δ函数平方模糊性的凝聚超势的推导。
