Monopole solutions in SU(2) YangMillsplusmassivenonlinearspinorfield theory
Abstract
Monopole solutions in SU(2) YangMills 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 HooftPolyakov monopole in that it is topologically trivial.
