Cosmic superstrings interact generically with a tower of light and/or strongly coupled Kaluza-Klein (KK) modes associated with the geometry of the internal space. We study the production of KK particles by cosmic superstring loops, and show that it is constrained by big bang nucleosynthesis. We study the resulting constraints in the parameter space of the underlying string theory model and highlight their complementarity with the regions that can be probed by current and upcoming gravitational wave experiments.
宇宙弦普遍与光塔和/或与内部空间几何相关的强耦合卡鲁扎-克莱因（KK）模式相互作用。我们研究了宇宙弦环产生的 KK 粒子，并表明它受到大爆炸核合成的限制。我们研究了基本弦理论模型参数空间中的结果限制，并强调了它们与当前和即将进行的引力波实验可探测区域的互补性。
