论文摘要
我们在开放式弦模型中分析了模量在量子级别的稳定性，以实现$ \ MATHCAL {n} = 2 \至\ MATHCAL {N} = 0 $在四维Minkowski SpaceTime中超对称性的自发断裂。在超对称断裂量表低于其他量表的模量空间的区域中，我们确定了一环有效电位的最小值消失，直到指数较小的校正。在这些背景下，频谱在无质量水平上满足玻色纤维脱位。
We analyze the stability of the moduli at the quantum level in an open-string model realizing the $\mathcal{N}=2\to \mathcal{N}=0$ spontaneous breaking of supersymmetry in four-dimensional Minkowski spacetime. In the region of moduli space where the supersymmetry breaking scale is lower than the other scales, we identify vanishing minima of the one-loop effective potential, up to exponentially small corrections. In these backgrounds, the spectrum satisfies Bose-Fermi degeneracy at the massless level.
