Special dyon-like black hole solution in the model with two Abelian gauge fields and two scalar fields
Dilatonic black hole dyon-like solution in the gravitational 4d model with two scalar fields and two 2-forms, governed by two 2-dimensional dilatonic coupling vectors obeying, i = 1, 2, is found. Some physical parameters of the solutions are obtained: gravitational mass, scalar charge, Hawking temperature, black hole area entropy and parametrized post-Newtonian (PPN) parameters β and γ. The PPN parameters do not depend on the coupling vectors A bound on the gravitational mass is proved. © Published under licence by IOP Publishing Ltd.
