Query: Baryon deceleration by strong chromofields in ultrarelativistic nuclear
  collisions   It is assumed that strong chromofields are generated at early stages of
ultrarelativistic heavy-ion collisions which give rise to a collective
deceleration of net baryons from colliding nuclei. We have solved classical
equations of motion for baryonic slabs under the action of a time-dependent
longitudinal chromoelectric field. It is demonstrated that the slab final
rapidities are rather sensitive to the strength and decay time of the
chromofield as well as to the back reaction of the produced partonic plasma.
The net-baryon rapidity loss of about 2 units, found for most central Au-Au
collisions at RHIC, can be explained by the action of chromofields with the
initial energy density of about 50 GeV/fm^3. Predictions for the baryon
stopping at the LHC are made.
