Abstract: (IOP)
We compute the one-loop world-sheet correction to partition function of AdS5×S5{\mathrm{AdS}}_{5}\times {{\rm{S}}}^{5} superstring that should be representing k-fundamental circular Wilson loop in planar limit. The 2d metric of the minimal surface ending on k-wound circle at the boundary is that of a cone of AdS(2) with deficit 2π(1k)2\pi (1-k). We compute the determinants of 2d fluctuation operators by first constructing heat kernels of scalar and spinor Laplacians on the cone using the Sommerfeld formula. The final expression for the k-dependent part of the one-loop correction has simple integral representation but is different from earlier results.
