Abstract

In this chapter vector-tensor (VT) theories are studied deriving the stationary spherically symmetric solution. In the absence of matter content, the solution obtained is similar to the Reissner-Nordström-de Sitter one of General Relativity, but the role of the electrical charge is played by some parameters related to the VT theory. Blackhole and cosmological horizons are also studied. A deviation of the radius of the VT black hole horizon with respect to the Kottler-Schwazschild-de Sitter one is found. Finally, from a study of the boundary conditions it is found that the cosmological constant appears in a natural way from these vector-tensor theories.
