| contents | Dilatonic black hole dyon-like solutions in the gravitational
$4d$ model with a scalar field, two 2-forms, two dilatonic coupling constants
$λ_i \neq 0$, $i =1,2$, obeying $λ_1 \neq - λ_2$
and the sign parameter $\varepsilon = \pm 1$ for scalar field kinetic term
are overviewed. Here $\varepsilon = - 1$ corresponds to a phantom scalar field.
The solutions are defined up to solutions of two master equations for two moduli functions, when
$λ^2_i \neq 1/2$ for $\varepsilon = - 1$. Several integrable cases
corresponding to Lie algebras $A_1 + A_1$, $A_2$, $B_2 = C_2$ and $G_2$ are considered.
Some physical parameters of the solutions are derived:
gravitational mass, scalar charge, Hawking temperature, black hole area entropy and
PPN parameters $β$ and $γ$. Bounds on the gravitational mass
and scalar charge (based on a certain conjecture) are presented. |
