Abstract

We formulate the BES/FRS equation as a functional equation in the rapidity space and perform its strong coupling expansion in the limit when ℓ=j/4g is kept finite. We obtain a result which is consistent with the previous calculations at tree level and one loop and which differs from the two-loop calculation in 0805.4615 by a term singular at ℓ=0.
