چکیده
|
We show the equality between macroscopic and microscopic (statistical) black hole entropy for a class of four dimensional non-supersymmetric black holes in $$ mathcal{n} $$ = 2 supergravity theory, up to the first subleading order in their charges. this solves a long standing entropy puzzle for this class of black holes. the macroscopic entropy has been computed in the presence of a newly derived higher-derivative supersymmetric invariant of [1], connected to the five dimensional supersymmetric weyl squared lagrangian. microscopically, the crucial role in obtaining the equivalence is played by the anomalous gauge gravitational chern-simons term.
