Operator Product Expansion of Wilson surfaces from M5-branes

Understand

The operator product expansion (OPE) of the Wilson surface operators in six-dimensional (2, 0) superconformal field theory is studied from AdS/CFT correspondence in this paper.

• We compute the OPE coefficients of the chiral primary operators using the M5-brane description for spherical Wilson surface operators in higher dimensional representations.
• We use the non-chiral M5-brane action in our calculation.
• We also discuss their membrane limit, and compare our results with the ones obtained from membrane description.
