Abstract:
We consider conformal N = 2 super Yang-Mills theories with gauge group
SU(N ) and Nf = 2N fundamental hypermultiplets in presence of a circular 1/2-BPS Wil-
son loop. It is natural to conjecture that the matrix model which describes the expectation
value of this system also encodes the one-point functions of chiral scalar operators in pres-
ence of the Wilson loop. We obtain evidence of this conjecture by successfully comparing,
at finite N and at the two-loop order, the one-point functions computed in field theory
with the vacuum expectation values of the corresponding normal-ordered operators in the
matrix model. For the part of these expressions with transcendentality ζ(3), we also obtain
results in the large-N limit that are exact in the ’t Hooft coupling λ.
