我们使用来自宇宙微波背景、大尺度结构和高红移氘的现有宇宙学数据来约束超对称和期限混合暴胀情景，包括宇宙弦对 CMB 各向异性的可能贡献。使用宇宙弦谱的两种不同实现，我们发现项模型的最小版本在高度显着性上被排除。项模型也与数据存在张力。我们还讨论了模型可能的非最小变体。
We use present cosmological data from the cosmic microwave background, large-scale structure and deuterium at high redshifts to constrain supersymmetric- and-term hybrid inflation scenarios including possible contributions to the CMB anisotropies from cosmic strings. Using two different realizations of the cosmic string spectrum, we find that the minimal version of the-term model is ruled out at high significance.-term models are also in tension with the data. We also discuss possible nonminimal variants of the models.
