The OPE coefficients are calculated in the large N and ${g}_{\mathrm{YM}}^{2}N$ limit by exploiting the AdS-CFT correspondence. We also consider Wilson surfaces in the (0,2), $d=6$ superconformal theory. In this case, we find that the UV divergent terms include a term proportional to the rigid string action.Read More
