AB We extend the analysis of KLWMIJ evolution in terms of QCD Reggeon fieldsbeyond leading order in the 1/Nc expansion. We show that there is only one type ofcorrections to the leading order Hamiltonian discussed in [1]. These are terms linear inoriginal Reggeons and quadratic in conjugate Reggeon operators. All of these have theinterpretation as vertices of the “‘merging”’ type 2 ! 1, where two Reggeons merge intoone. Importantly, the triple Pomeron merging vertex does not emerge from the KLWMIJHamiltonian. We show that, although in the range of applicability of the KLWMIJ Hamiltonianthese merging terms are subleading in Nc, in the dense-dense regime they all becomeof the same (leading) order in Nc. In this regime vertices involving higher Reggeons areenhanced by inverse powers of the coupling constant
