Multicentered solution for maximally charged dilaton black holes in arbitrary dimensions

A family of static multicentered solutions to modified Einstein-Maxwell equations coupled with a dilaton is constructed in $(1+N)$ dimensional space-time ($N\ge 2$). For $N\ge 3$, the solutions are generalizations of the Majumdar-Papapetrou solution. We also find the solution in $(1+2)$ dimensions, where the scalar and vector forces cancel each other in the static case. The interaction between two extreme charged dilaton black holes in the low-energy limit is investigated in $(1+N)$ dimensions ($N\ge 3$). We find that there remains the residual velocity-dependent force in general cases, except for the case with $N=a^2$.
