  With the HIJING/BBbar v2.0 heavy ion event generator, we explore the
phenomenological consequences of several high parton density dynamical effects
predicted in central Pb+Pb collisions at the Large Hadron Collider (LHC)
energies. These include (1) jet quenching due to parton energy loss (dE/dx),
(2) strangeness and hyperon enhancement due to strong longitudinal color field
(SCF), and (3) enhancement of baryon-to-meson ratios due to baryon-anti-baryon
junctions (JJbar) loops and SCF effects. The saturation/minijet cutoff scale
p0(s)and effective string tension kappa(s,A) are constrained by our previous
analysis of LHC p+p data and recent data on the charged multiplicity for Pb+Pb
collisions reported by the ALICE collaboration. We predict the hadron flavor
dependence (mesons and baryons) of the nuclear modification factor RAA(pT)$ and
emphasize the possibility that the baryon anomaly could persist at the LHC up
to pT=10 GeV, well beyond the range observed in central Au+Au collisions at
RHIC energies.
