TL;DR
This paper investigates how fermionic corrections influence the attractor mechanism in N=2, D=4 supergravity, revealing new contributions to scalar field values at the black hole horizon.
Contribution
It introduces the first computation of fermionic modifications to the attractor mechanism at fourth order in supergravity.
Findings
Fermionic corrections alter the horizon values of scalar fields.
A new contribution to the attractor mechanism is identified.
The results deepen understanding of fermionic effects in supergravity.
Abstract
We compute the modifications to the attractor mechanism due to fermionic corrections. In N=2, D=4 supergravity, at the fourth order, we find a new contribution to the horizon values of the scalar fields of the vector multiplets.
