  The suppression of hadron production originated from the induced jet energy
loss is one of the most accepted and well understood phenomena in heavy ion
collisions, which indicates the formation of color deconfined matter consists
of quarks, antiquarks and gluons. This phenomena has been seen at RHIC energies
and now the first LHC results display a very similar effect. In fact, the
suppression is so close to each other at 200 AGeV and 2.76 ATeV, that it is
interesting to investigate if such a suppression pattern can exist at all. We
use the Gyulassy-Levai-Vitev description of induced jet energy loss combined
with different nuclear shadowing functions and describe the experimental data.
We claim that a consistent picture can be obtained for the produced hot matter
with a weak nuclear shadowing. The interplay between nuclear shadowing and jet
energy loss playes a crucial role in the understanding of the experimental
data.
