Description

I will display the generalisation of solutions describing bound states of interacting non-BPS extremal black holes to N=8 supergravity. I will explain in particular how gravitini N=2 multiplets vector fields and some hyper-multiplets scalars are involved in a non-trivial manner in these solutions. For this purpose I will define `special coordinates' for the N=8 moduli which generalise naturally the special Kaehler coordinates. Then I will display some physical properties of these solutions, and in particular the existence of three by three interactions that are absent in the BPS solutions, and which are responsible for an extra contribution to the ADM angular momentum.
