Nuclear modification of high-p_T hadron spectra in p+A collisions at LHC
Multiple parton scatterings in high-energy p+A collisions involve
multi-parton correlation inside the projectile and color coherence of multiple
jets which will lead to nuclear modification of final hadron spectra relative
to that in p+p collisions. Such modification of final hadron spectra in p+A
collisions is studied within HIJING 2.1 model which includes initial parton
shadowing, transverse momentum broadening, parton flavor and momentum
correlation inside the projectile through flavor and momentum conservation and
fragmentation of multiple jets. They are shown to modify the partonic flavor
content of final jets and momentum spectra of final hadrons in p+A collisions
at the Large Hadron Collider.Comment: 4 pages in RevTex with 4 figures, LHC pPb collision energy is changed

Hadron production in p+p, p+Pb, and Pb+Pb collisions with the HIJING 2.0 model at energies available at the CERN Large Hadron Collider
The HIJING (Heavy-ion Jet Interaction Generator) Monte Carlo model is updated
with the latest parton distributions functions (PDF) and new set of the
parameters in the two-component mini-jet model that controls total cross
section and the central pseudorapity density. We study hadron spectra and
multiplicity distributions using the HIJING 2.0 model and compare to recent
experimental data from collisions at the LHC energies. We also give
predictions of hadron production in , and collisions at the
full LHC energy.Comment: 9 pages in RevTex with 11 postscript figures, updated with new
results and some new data are included in comparison. The title is changed in
