J. Jalilian-marian et al., Wilson renormalization group for low x physics: Gluon evolution at finite parton density - art. no. 014015., PHYS REV D, 5901(1), 1999, pp. 4015
In this paper we derive the complete Wilson renormalization group equation
which governs the evolution of the gluon distribution and other gluonic obs
ervables at low x and arbitrary density. [S0556-2821(98)02823-9].
