Query: Non-linear QCD evolution with improved triple-pomeron vertices   In a previous publication, we have constructed a set of non-linear evolution
equations for dipole scattering amplitudes in QCD at high energy, which extends
the Balitsky-JIMWLK hierarchy by including the effects of fluctuations in the
gluon number in the target wavefunction. In doing so, we have relied on the
color dipole picture, valid in the limit where the number of colors is large,
and we have made some further approximations on the relation between scattering
amplitudes and dipole densities, which amount to neglecting the non-locality of
the two-gluon exchanges. In this Letter, we relax the latter approximations,
and thus restore the correct structure of the `triple-pomeron vertex' which
describes the splitting of one BFKL pomeron into two within the terms
responsible for fluctuations. The ensuing triple-pomeron vertex coincides with
the one previously derived by Braun and Vacca within perturbative QCD. The
evolution equations can be recast in a Langevin form, but with a multivariable
noise term with off-diagonal correlations. Our equations are shown to be
equivalent with the modified version of the JIMWLK equation recently proposed
by Mueller, Shoshi, and Wong.
