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 m22m^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 m22m_2^2\to\infty leads to the series form of the charged BBMB black hole solution. However, for m22<0m^2_2<0, we could not obtain any asymptotically flat black hole solution with scalar hair.
