Correlators of supersymmetric Wilson loops at weak and strong coupling

Bassetto, Antonio, Griguolo, Luca, Pucci, Fabrizio et al.

Understand

We continue our study of the correlators of a recently discovered family of BPS Wilson loops in N=4 supersymmetric U(N) Yang-Mills theory.

  • We perform explicit computations at weak coupling by means of analytical and numerical methods finding agreement with the exact formula derived from localization.
  • In particular we check the localization prediction at order g^6 for different BPS "latitude" configurations, the N=4 perturbative expansion reproducing the expected results within a relative error of 10^(-4).
  • On the strong coupling side we present a supergravity evaluation of the 1/8 BPS correlator in the limit of large separation, taking into account the exchange of all relevant modes between the string world-sheets.
