The results of General Relativity are reproduced in the $\omega_{\textrm{BD}},\omega_0\to\infty$ limit. The numerical solutions correspond to a soliton star with a non-abelian gauge field. We study the effects of the coupling constant, the frequency of the Higgs field and the Brans-Dicke field on the soliton parameters Description Reference: Phys.Rev.
