Monopole and dyon supermultiplets

Abstract:

The structure of monopole and dyon supermultiplets is elucidated in some supersymmetric gauge theories which admit classical monopole solutions. Our particular emphasis is on the phenomenon of fermion fractionization in supersymmetric theories. It is shown that in the N=1 and N=2 supersymmetric Georgi-Glashow models the occurrence of the fermion fractionization is the necessity; the ignorance of it results in the inconsistency in the perturbative calculation of the mass splittings among the members of the supermultiplets. The notable feature of our result is that the degeneracy due to the Jackiw-Rebbi zero mode is not independent of the one required by the supersymmetry, suggesting a nontrivial structure in embedding the topology of Higgs fields into supersymmetric gauge theories. © 1985 The American Physical Society.
