A holographic computation of the central charges of d=4, N=2 SCFTs

Understand

We use the AdS/CFT correspondence to compute the central charges of the d=4, N=2 superconformal field theories arising from N D3-branes at singularities in F-theory.

• These include the conformal theories with E_n global symmetries.
• We compute the central charges a and c related to the conformal anomaly, and also the central charges k associated to the global symmetry in these theories.
• All of these are related to the coefficients of Chern-Simons terms in the dual string theory on AdS_5.
