Static spherically symmetric solution for the field of a charged particle in a theory of gravity

The field equations for a new theory of gravity are derived from a variational principle when electromagnetic fields are included in the Lagrangian density L. A static spherically symmetric solution to the field equations is obtained, which reduces to the Reissner-Nordstr\"om solution when a new gravitational coupling constant l equals zero. For l>m+(m²-4πQ²)1/2 black-hole event horizons are excluded from physical space-time.
