Monopole solutions in SU(2) Yang-Mills-plus-massive-nonlinear-spinor-field theory
Abstract
Monopole solutions in SU(2) Yang-Mills theory which includes spinor fields described by the nonlinear Dirac equation are obtained. It is demonstrated that the energy spectrum of such a system possesses a global minimum whose appearance is brought about solely by the nonlinear spinor fields. It is shown that the monopole solution obtained differs in principle from the 't Hooft-Polyakov monopole in that it is topologically trivial.
