We found a new constraint involving the loop momenta along the competition axis, which allows to solve the two-loop integrals. The exponent $γ_{L2}$ obtained using our method is in good agreement with numerical estimates based on Monte Carlo simulations.18 pages, Revtex, updated version with four figures, some references addedCondensed MatterHigh Energy Physics - Theorytext
