Query: Exact Black-Hole Solution With Self-Interacting Scalar Field   Einstein gravity minimally coupled to a self-interacting scalar field is
investigated in the static and isotropic situation. We explicitly construct in
partially closed form a new black-hole solution with exponentially decaying
scalar hair. The symmetric interaction potential has both signs and a
triple-well shape with a smooth but non-analytic minimum at vanishing field. We
present numerical data as well as double series expansions around spatial
infinity.
