Abstract

New solutions to the static, spherically symmetric Einstein-Yang-Mills- Higgs equations with the Higgs field in the triplet (doublet) representation are presented. They form continuous families parametrized by α=MW/MPl [MW (MPl) denoting the W boson (the Planck) mass]. The corresponding spacetimes are regular and have spatially compact sections. A particularly interesting class with the Yang-Mills amplitude being nodeless is exhibited and is shown to be linearly stable with respect to spherically symmetric perturbations. For some solutions with nodes of the Yang-Mills amplitude a new stabilization phenomenon is found, according to which their unstable modes disappear as α increases (for the triplet) or decreases (for the doublet).
