heal.abstract |
We study Einstein-Yang-Mills equations in the presence of a gravitating nontopological soliton field configuration consisting of a Higgs doublet, in Brans-Dicke and general scalar-tensor gravitational theories. The results of General Relativity are reproduced in the ωBD, ω0 → ∞ 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. © 2005 The American Physical Society. |
