Static Black Hole dressed with a massive Scalar field
  A four-dimensional static black hole solution of Einstein equation conformally coupled to a massive and self interacting scalar field is obtained. A nontrivial scalar solution proposes a weak scalar hair. A dressed black hole shows a trace of scalar charge in the metric signalling the presence of scalar hair. A number of metrics with regular horizons and temperatures are also proposed.
