Exact fermion-dyon scattering solutions

We analyze the Dirac equation for an I = (1/2) fermion in the field of an SU(2) Julia-Zee dyon. In the Prasad-Sommerfield limit we obtain exact J = 0 partial-wave solutions for massless fermions. These solutions describe charge-exchange scattering as well as dyon decay via charged-fermion-pair emiss...

Zusammenfassung:	We analyze the Dirac equation for an I = (1/2) fermion in the field of an SU(2) Julia-Zee dyon. In the Prasad-Sommerfield limit we obtain exact J = 0 partial-wave solutions for massless fermions. These solutions describe charge-exchange scattering as well as dyon decay via charged-fermion-pair emission. When the initial fermion-dyon Coulomb interaction is repulsive, low-momentum single-particle J = 0 scattering is prohibited. Implications of our results for proton decay catalysis by SU(5) dyons are briefly discussed.
