Cardy limits of 6d superconformal theories

Abstract

Abstract We explore the supersymmetric partition functions of 6d SCFTs on ℝ4 × T 2 with non-vanishing charges for compatible global symmetries. We utilize the elliptic genera for self-dual strings and compute the free energy of 6d SCFTs in the Cardy limit. For a 6d (2,0) theory on N M5-brane, we obtain the free energy proportional to N 3. We find that the origin of N 3 comes from the condensation of the self-dual strings, whose total number is proportional to N 3 − N 6 $$ \frac{N^3-N}{6} $$ . We further extend our analysis to the general E-string theory and obtain its Cardy free energy.
