Resumo

Using the ideas from the BPS/CFT correspondence, we give an explicit recursive
formula for computing supersymmetric Wilson loop averages in 3d N = 2
Yang-Mills-Chern-Simons U(N) theory on the squashed sphere S^3_b with one
adjoint chiral and two antichiral fundamental multiplets, for specific values
of Chern-Simons level k2 and Fayet-Illiopoulos parameter k1. For these values
of k1 and k2 the north and south pole turn out to be completely independent,
and therefore Wilson loop averages factorize into answers for the two
constituent D^2×S^1 theories. In particular, our formula provides results for
the theory on the round sphere when the squashing is removed.
