Black hole with primary scalar hair in Einstein-Weyl-Maxwell-conformal scalar theory

Abstract

We obtain a newly charged BBMB (Bocharova-Bronnikov-Melnikov-Bekenstein) black hole solution from the Einstein-Weyl-Maxwell-conformal (conformally coupled) scalar theory with a positive Weyl coupling parameter $m_2^2$ numerically. This solution has a primary scalar hair, compared to a secondary scalar hair in the charged BBMB black hole solution. The limiting case of $m_2^2\to \infty$ leads to the series form of the charged BBMB black hole solution. However, for $m_2^2<0$, we could not obtain any asymptotically flat black hole solution with scalar hair.
