d=4 attractors, effective horizon radius, and fake supergravity

We consider extremal black hole attractors [both Bogomol'nyi- Prasad- Sommerfield (BPS) and nonBPS] for N = 3 and N = 5 supergravity in d = 4 space- time dimensions. Attractors for mattercoupled N = 3 theory are similar to attractors in N = 2 supergravity minimally coupled to Abelian vector multiplets. On the other hand, N = 5 attractors are similar to attractors in N = 4 pure supergravity, and in such theories only 1/N-BPS nondegenerate solutions exist. All the above- mentioned theories have a simple interpretation in the first order ( fake supergravity) formalism. Furthermore, such theories do not have a d 5 uplift. Finally we comment on the duality relations among the attractor solutions of N >= 2 supergravities sharing the same full bosonic sector.
