The S-matrix for a spin 1/2 particle in the presence of a potential which is the sum of the Coulomb potential Vc = −A1/r and a Lorentz scalar potential Vs = −A2/r is calculated. PACS numbers:03.65.Pm,11.80.-m ⋆ e-mail:[email protected]

We consider the Einstein-Yang-Mills-Higgs equations for an SU(3) gauge group in a spherically symmetric ansatz. Several properties of the gravitating monopole solutions are obtained an compared with their SU(2) counterpart.
