Black holes cannot support conformal scalar hair

arXiv:gr-qc/9409030 · doi:10.1063/1.531201

Abstract

It is shown that the only static asymptotically flat non-extrema black hole solution of the Einstein-conformally invariant scalar field equations having the scalar field bounded on the horizon, is the Schwarzschild one. Thus black holes cannot be endowed with conformal scalar hair of finite length.
