Matching quantum string corrections and circular Wilson loops in AdS4 × CP3

Recent progresses in the computation of quantum string corrections to holographic Wilson loops are extended to the case of strings in AdS4 × CP3.

Explicit evaluation of fluctuation determinants using phaseshifts and diffeomorphism in-variant regulators leads to exact matching with the recent field theory proposal. Key to this computation is the choice of boundary conditions for massless fermions. In the limit for which the latitude Wilson loop has a trivial expectation value, the long known localization result for the 12\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$ \frac{1}{2} $$\end{document}-BPS fermionic circular Wilson loop in ABJM is recovered.
