论文摘要
提出了将统一的黑暗扇区模型嵌入带有以下特征的字符串理论中的：与kalb-ramond 2form场降低的轴轴是用深色磁场鉴定出来的，而kähller模量场的真实部分 - “半径”的“半径”，“ radius”''''''''''''''''radius'''''''''''''''''''' DILATON场的期望值通过仪表式冷凝机制稳定。对应于现实的低能尺度的深度能力是由于对Dilaton的稳定期望值的一些温和调整而产生的。由此产生的潜力再现了我们两个人提出的先前黑暗扇区模型中的一个。
An embedding of a unified dark sector model into string theory with the following features is proposed: The model-independent axion descending from the Kalb-Ramond 2-form field is identified with the dark-matter field, and the real part of a Kähler modulus field -- the ``radius'' of one of the extra spatial dimensions -- accounts for dark energy. The expectation value of the dilaton field is stabilized by a gaugino condensation mechanism. A dark-energy potential corresponding to a realistic low energy scale results from some gentle tuning of the stabilized expectation value of the dilaton. The resulting potential reproduces the one in a previous dark-sector model proposed by two of us.
