Abstract
We calculate the away-side hadron-triggered modification factor IAA
in AA collisions at RHIC and LHC energies for
scenarios with and without quark-gluon plasma formation in pp
collision.
We find that for both scenarios
theoretical results for IAA agree well with the available data
for 2.76 TeV Pb + Pb and 0.2 TeV Au + Au collisions.
We make predictions for IAA in 7 TeV O + O collisions
that are planned at the LHC.
Our results show that measuring IOO in the whole
centrality interval and at small centrality (
may give information on the presence of jet quenching
in pp collisions.
