 note = {It is known that the expectation value of Wilson loops in the Gross-Witten-Wadia (GWW) unitary matrix model can be computed exactly at finite N for arbitrary representations. We study the perturbative and non-perturbative corrections of Wilson loops in the 1/N expansion, either analytically or numerically using the exact result at finite N. As a by-product of the exact result of Wilson loops, we propose a large N master field of GWW model. This master field has an interesting eigenvalue distribution. We also study the Wilson loops in large representations, called Giant Wilson loops, and comment on the Hagedorn/deconfinement transition of a unitary matrix model with a double trace interaction., Article, JOURNAL OF HIGH ENERGY PHYSICS.(7):30(2017)},
