BPS Wilson loop in $\mathcal N=2$ superconformal $SU(N)$ "orientifold" gauge theory and weak-strong coupling interpolation

Abstract: We consider the expectation value xWy of the circular BPS Wilson loop in N " 2 superconformal SU pN q gauge theory containing a vector multiplet coupled to two hypermultiplets in rank-2 symmetric and antisymmetric representations. This theory admits a regular large N expansion, is planar-equivalent to N " 4 SYM theory and is expected to be dual to a certain orbifold/orientifold projection of AdS 5 ˆS5 superstring theory. On the string theory side xWy is represented by the path integral expanded near the same A… Show more

“…It is quite remarkable that, as observed in [8], this is essentially the same matrix 6 appearing in the analysis of the zeros of Bessel functions performed in [47]. Note that the main diagonal and the super-and sub-diagonals of S converge to 0 when the size of the matrix increases.…”

“…where δ U is a non-trivial function of the 't Hooft coupling. The free energy and the vacuum expectation value of the BPS Wilson loop are examples of untwisted observables [8,22,38] but, as we will see, also the correlators of gauge invariant single-trace operators with even dimension in the E theory belong to the untwisted class.…”

“…The action of supersymmetric localization in N = 2 is still powerful enough to reduce the Wilson loop vacuum expectation value (vev) to a matrix model, even though it is no longer Gaussian. Several quantities have been analysed for N = 2 theories, such as the Wilson loop vev [31][32][33][34][35] together with correlators of chiral operators and Wilson loops [36][37][38] and the Bremsstrahlung function [39][40][41].…”
