PAULI EQUATION FOR SPIN-1 2 DYONIUM IN NON-ABELIAN GAUGE-THEORY/

The study of the behaviour of a spin-1/2 non-Abelian dyon moving in th e field of an Abelian dyon has been undertaken by solving Dirac equati on for energy eigenvalues. The Hamiltonian of this system has been sho wn to involve spin as well as the contribution of massive fields assoc iated with these particles. By introducing suitable spinors, the Pauli equation for a spin-1/2 dyon moving in the field of another dyon has been solved in non-Abelian gauge theory. It is shown that the introduc tion of massive fields perceptibly modifies the energy eigenvalue and eigenfunction of the bound state of the system.
