Radiative diquark energy loss from induced gluon emission can partially fill the midrapidity dip in the net proton rapidity distribution in central AA collisions at sqrt(s) ~ 10 GeV, with the effect's size strongly dependent on the assumed gluon mass.

abstract
We derive a generalized Balitskii-Fadin-Kuraev-Lipatov equation, which applies directly to the perturbative QCD component of total cross section. With the gluon correlation radius $R_{c} \sim 0.4$f we reproduce the empirical rate of growth of the hadron-nucleon total cross sections. The simultaneous estimate of the triple-pomeron coupling also agrees with the experiment.

Radiative parton energy loss and baryon stopping in $AA$ collisions
Radiative diquark energy loss from induced gluon emission can partially fill the midrapidity dip in the net proton rapidity distribution in central AA collisions at sqrt(s) ~ 10 GeV, with the effect's size strongly dependent on the assumed gluon mass.
