Abstract
We study the radiative energy loss contribution to
proton stopping in AA collisions.
The analyses is performed within the light-cone path integral approach
to induced gluon emission.
We have found that the radiative correction can fill in partly the
midrapidity dip in the net proton rapidity distribution in AA
collisions at
GeV.
We argue that at GeV the net proton fluctuations
at midrapidity may be dominated by the initial fluctuations of
the proton flow, which, to a good accuracy, should be binomial.
