INTERACTION ENERGY OF T-HOOFT-POLYAKOV MONOPOLES

The dependence of the energies of axially symmetric monopoles of magne tic charges 2 and 3, on the Higgs self-interaction coupling constant, is studied numerically. Comparing the energy per unit topological char ge of the charge-a monopole with the energy of the spherically symmetr ic charge-1 monopole, we confirm that there is only one repulsive phas e in the interaction energy between like monopoles.
