Spin and isospin in a gauge theory with monopoles
Authors:W. Troost  P. Vinciarelli
Affiliation:CERN, Geneva, Switzerland
Abstract:The mechanism by which systems of spinless bosons with isospin and spinless magnetic monopoles acquire a spin in their ground states is investigated in the context of SU(2) gauge models. Contrary to recent claims, it is demonstrated that isospin degrees of freedom are not converted into spin degrees of freedom. For a spin 12 state, solutions are explicitly constructed, exhibiting the isospin degree of freedom.
