  We discuss new physical phenomena expected in particle production in
hadron-hadron collisions at high energy, as a consequence of Pomeron loop
effects in the evolution equations for the Color Glass Condensate. We focus on
gluon production in asymmetric, `dilute-dense', collisions : a dilute
projectile scatters off a dense hadronic target, whose gluon distribution is
highly evolved. This situation is representative for particle production in
proton-proton collisions at forward rapidities (say, at LHC) and admits a
dipole factorization similar to that of deep inelastic scattering (DIS). We
show that at sufficiently large forward rapidities, where the Pomeron loop
effects become important in the evolution of the target wavefunction, gluon
production is dominated by `black spots' (saturated gluon configurations) up to
very large values of the transverse momentum, well above the average saturation
momentum in the target. In this regime, the produced gluon spectrum exhibits
diffusive scaling, so like DIS at sufficiently high energy.
