Zeta-function regularization of holographic Wilson loops

Using ζ-function regularization, we study the one-loop effective action of fundamental strings in AdS5×S5 dual to the latitude 14-BPS Wilson loop in N=4 super-Yang-Mills theory. To avoid certain ambiguities inherent to string theory on curved backgrounds we subtract the effective action of the holog...

Description
Summary:Using ζ-function regularization, we study the one-loop effective action of fundamental strings in AdS5×S5 dual to the latitude 14-BPS Wilson loop in N=4 super-Yang-Mills theory. To avoid certain ambiguities inherent to string theory on curved backgrounds we subtract the effective action of the holographic 12-BPS Wilson loop. We find agreement with the expected field theory result at first order in the small latitude angle expansion but discrepancies at higher order.
