We construct an exact solution to the revised small-x orbital angular momentum (OAM) evolution equations derived in [1], based on an earlier work [2]. These equations are derived in the double logarithmic approximation (summing powers of α_s ln²(1/x) with α_s the strong coupling constant and x the Bjorken x variable) and the large-N_c limit, with N_c the number of quark colors. From our solution, we extract the small-x, large-N_c expressions of the quark and gluon OAM distributions.
