我们考虑在膨胀的宇宙中弦网络的演化,允许不同张力的弦之间形成连接。通过明确地包括,在网络的速度相关的演化方程,运动学约束与形成Y形串结,我们展示了他们如何导致缩放的解决方案,否则他们不会被发现的制度,从而扩展的范围内的参数,导致缩放。通过结合这些约束,我们能够研究它们在具有宇宙超弦相互作用规则的网络中的一般行为,并预测这些网络所期望的标度密度。
We consider the evolution of a network of strings in an expanding Universe, allowing for the formation of junctions between strings of different tensions. By explicitly including, in the velocity-dependent evolution equations for the network, kinematic constraints associated with the formation of Y-shaped string junctions, we show how they lead to scaling solutions in regimes where they would not otherwise be found, thereby extending the range of parameters which lead to scaling. By incorporating these constraints we are able to study their general behavior for networks with cosmic superstring interaction rules, and predict the scaling densities expected by these networks.
