摘要
Dilatonic black hole dyon-like solutions in the gravitational 4d model with a scalar field, two 2-forms, two dilatonic coupling constants lambda(i) not equal 0, i = 1, 2, obeying lambda(1) not equal -lambda(2) and the sign parameter epsilon = +/- 1 for scalar field kinetic term are considered. Here epsilon = -1 corresponds to a ghost scalar field. These solutions are defined up to solutions of two master equations for two moduli functions, when lambda(2)(i) not equal 1/2 for epsilon = -1. Some physical parameters of the solutions are obtained: gravitational mass, scalar charge, Hawking temperature, black hole area entropy and parametrized post-Newtonian (PPN) parameters beta and gamma. The PPN parameters do not depend on the couplings lambda(i) and epsilon. Aset of bounds on the gravitational mass and scalar charge are found by using a certain conjecture on the parameters of solutions, when 1 + 2 lambda(2)(i) epsilon > 0, i = 1, 2.
