Formation of Non-Abelian Monopoles Connected by Strings
Yifung Ng, T. W. B. Kibble, Tanmay Vachaspati
We study the formation of monopoles and strings in a model where SU(3) is spontaneously broken to U(2)=[SU(2)\times U(1)]/\ZZ_2, and then to U(1). The first symmetry breaking gener…
On the Collision of Cosmic Superstrings
E. J. Copeland, H. Firouzjahi, T. W. B. Kibble +1
We study the formation of three-string junctions between (p,q)-cosmic superstrings, and collisions between such strings and show that kinematic constraints analogous to those found…
Kinematic Constraints on Formation of Bound States of Cosmic Strings - Field Theoretical Approach
P. Salmi, A. Achucarro, E. J. Copeland +3
Superstring theory predicts the potential formation of string networks with bound states ending in junctions. Kinematic constraints for junction formation have been derived within…
Collisions of strings with Y junctions
E. J. Copeland, T. W. B. Kibble, D. A. Steer
We study the dynamics of Nambu--Goto strings with junctions at which three strings meet. In particular, we exhibit one simple exact solution and examine the process of intercommuti…
Fundamental cosmic strings
A. -C. Davis, T. W. B. Kibble
Cosmic strings are linear concentrations of energy that may be formed at phase transitions in the very early universe. At one time they were thought to provide a possible origin fo…
