Power—law mass inflation in Einstein—Yang—Mills—Higgs black holes

Abstract

Analytical formulas are presented describing a generic singularity inside static spherically symmetric black holes in the SU(2) Einstein—Yang—Mills—Higgs theory with a triplet and/or doublet Higgs field. The singularity is spacelike and exhibits a ‘power-low mass inflation’. Alternatively this asymptotic behavior may be interpreted as a pointlike singularity in the Kantowski-Sachs closed anisotropic cosmology.
