The flavor dependence of the medium modification factor R pp for pp collisions has been studied for a scenario with formation of a small-size quark-gluon plasma (QGP) for RHIC ( √ s = 0.2 TeV) and LHC ( √ s = 2.76 TeV) energies. It has been found that at p T ~ 10 GeV the pion spectrum is suppressed by ~20–30 (25–35)% for RHIC (LHC), for D (B) mesons the suppression effect is smaller by a factor of ~0.7–0.8 (0.5). The flavor hierarchy R π < R < R is held at p T ≲ 20 GeV for RHIC and at p T ≲ 70 GeV for LHC. This gives a significant reduction of the heavy-to-light ratios of the nuclear modification factors R AA as compared to that in the standard scenario without the QGP production in pp collisions.
