| Résumé : | We analyze the fermionic wigging of 1/2-BPS (electric) extremal black hole attractors in N=2, D = 5 ungauged Maxwell-Einstein supergravity theories, by exploiting anti-Killing spinors supersymmetry transformations. Regardless of the specific data of the real special geometry of the manifold defining the scalars of the vector multiplets, and differently from the D = 4 case, we find that there are no corrections for the near-horizon attractor value of the scalar fields; an analogous result also holds for 1/2-BPS (magnetic) extremal black string. Thus, the attractor mechanism receives no fermionic corrections in D = 5 (at least in the BPS sector). © 2014 Elsevier B.V. |
