翘曲紧化中的宇宙超弦轨迹

Cosmic superstring trajectories in warped compactifications

Anastasios Avgoustidis, Sarah Chadburn, Ruth Gregory

摘要:

我们探讨宇宙(超)弦的通用运动时,内部紧凑的尺寸是扭曲的,使用Klebanov-Strassler解决方案作为一个原型喉几何。我们发现,没有动力学机制,本地化的字符串在喉咙的尖端,而是运动似乎探索内部和外部的自由度民主。这表明,由暴胀膜-反膜湮灭形成的宇宙(超弦)将有足够的内部运动,使得来自弦网络的引力波信号相对于来自“标准”宇宙弦网络的信号被抑制。

英文摘要:

We explore the generic motion of cosmic (super)strings when the internal compact dimensions are warped, using the Klebanov-Strassler solution as a prototypical throat geometry. We find that there is no dynamical mechanism which localises the string at the tip of the throat, but rather that the motion seems to explore both internal and external degrees of freedom democratically. This indicates that cosmic (super)strings formed by inflationary brane-antibrane annihilation will have sufficient internal motion for the gravitational wave signals from the string network to be suppressed relative to the signal from a `standard' cosmic string network.
