Defect correlators in a N $$ \mathcal{N} $$ = 2 SCFT at strong coupling

Abstract We study the correlation function between one single-trace scalar operator and a circular Wilson loop in the 4d N $$ \mathcal{N} $$ = 2 superconformal field theory with gauge group SU(N) and matter transforming in the symmetric and anti-symmetric representations.

Description
Summary:Abstract We study the correlation function between one single-trace scalar operator and a circular Wilson loop in the 4d N $$ \mathcal{N} $$ = 2 superconformal field theory with gauge group SU(N) and matter transforming in the symmetric and anti-symmetric representations. By exploiting supersymmetric localization, we resum the perturbative expansion of this correlator in the large-N ’t Hooft limit. Furthermore, using both analytical and numerical techniques, we provide a prediction for the leading term of its strong coupling expansion and we compare this prediction to numerical Padé resummations of the perturbative series.
