Electric Fields and Chiral Magnetic Effect in Cu + Au Collisions
The non-central Cu + Au collisions can create strong out-of-plane magnetic
fields and in-plane electric fields. By using the HIJING model, we study the
general properties of the electromagnetic fields in Cu + Au collisions at 200
GeV and their impacts on the charge-dependent two-particle correlator
(see main text for
definition) which was used for the detection of the chiral magnetic effect
(CME). Compared with Au + Au collisions, we find that the in-plane electric
fields in Cu + Au collisions can strongly suppress the two-particle correlator
or even reverse its sign if the lifetime of the electric fields is long.
Combining with the expectation that if is induced by
elliptic-flow driven effects we would not see such strong suppression or
reversion, our results suggest to use Cu + Au collisions to test CME and
understand the mechanisms that underlie .Comment: V1: 7 pages, 8 figures. V2: Add 2 new figures. Published versio
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
