2-loop free energy of M2 brane in AdS7 × S 4 and surface defect anomaly in (2,0) theory
Abstract 1 2 $$ \frac{1}{2} $$ -BPS surface operator viewed as a conformal defect in rank N 6d (2,0) theory is expected to have a holographic description in terms of a probe M2 brane wrapped on AdS3 in the AdS7 × S 4 M-theory background. The M2 brane has the effective tension T2 = 2 π $$ \frac{2}{\p...
