Cosmic strings with junctions

If cosmic superstrings are formed, they necessarily come in two different types which can interact with each other and become entangled, thus forming Y-shaped junctions. This is a novel property, not present in the conventional cosmic string scenario, and an interesting question is how the presence of junctions affects the dynamics of a cosmic superstring network. We focus on the evolution and stability of cosmic strings with junctions, and we discuss potential observational consequences.
