  In the framework of the HIJING model global characteristics of nucleus-
nucleus collisions are studied for a Large Hadron Collider energy scale. An
interesting model prediction is the presence of a central bump over a
pseudorapidity plateau of a total transverse energy distribution. The bump is
induced by a jet quenching effect in a dense nuclear matter. It is shown that
on a wide acceptance calorimeter with a pseudorapidity coverage
  -5 < \eta < 5 allow to obtain experimental confirmation of such an effect.
