Abstract: (Elsevier)
We consider a class of closed stringlike configurations, called essentially knotted , which occur in certain (3 + 1)-dimensional Yang-Mills-Higgs theories where a compact gauge group G breaks to a finite, nonabelian subgroup H. Such objects are labelled by more than one flux element in H, and cannot be deformed into the vacuum without overlapping the cores of two segments of string carrying noncommuting fluxes. Analogous results for multicomponent links of string are also given. Our analysis is performed within a general topological framework for discussing the knotting and linking of strings in spontaneously broken gauge theories.- gauge field theory: Yang-Mills
