  I discuss the p_t distributions for high-multiplicity events originating from
semi-classical variation of the gluon density of the proton.The multiplicity
distribution measures the curvature of the effective action for the small-x
gluon fields. For pA collisions at the RHIC and LHC colliders, semi-classically
the multiplicity distribution reflects the distribution of saturation momenta
of the proton but not that of the nucleus. The average transverse momentum in
the central region grows with dN/dy, while the p_t distribution of leading
hadrons in the proton fragmentation region should depend less on the
multiplicity in the central region.
