We compute the one-loop world-sheet correction to partition function of$AdS_5 \times S^5$ superstring that should be representing $k$-fundamentalcircular Wilson loop in planar limit. The 2d metric of the minimal surfaceending on $k$-wound circle at the boundary is that of a cone of $AdS_2$ withdeficit $2\pi (1-k)$. We compute determinants of 2d fluctuation operators byfirst constructing heat kernels of scalar and spinor Laplacians on the coneusing the Sommerfeld formula. The final expression for the k-dependent part ofthe one-loop correction has simple integral representation but is differentfrom earlier results.
