摘要：

We explore the stability of semilocal string numerically. Our results confirm the conclusions of Hindmarsh and also show a range of asymptotic field configurations that will relax to the semilocal string configuration rather than to the trivial vacuum. We also study field configurations corresponding to two semilocal strings with different colours and find that the colour rapidly equilibrates and has little effect on the dynamics of the strings. This result and its limitations are discussed and implications for the evolution of the semilocal string network are drawn. In addition, we construct models that contain monopoles labelled by colour indices.
