Abstract We study the flavor dependence of the medium modification
factor Rpp for pp collisions for scenario with formation of a
small-size quark-gluon plasma (QGP) for RHIC ( TeV)
and LHC ( TeV) energies.
We find that at GeV
the pion spectrum is suppressed by
for RHIC (LHC), for D (B) mesons the suppression
effect is smaller by a factor of (0.5).
The flavor hierarchy Rppπ<RppD<RppB
is held at GeV for RHIC and at GeV
for LHC. This gives a sizeable reduction of the
heavy-to-light ratios of the nuclear modification factors RAA
as compared to that in the standard scenario without
the QGP production in pp collisions.
