Relativistic light-on-heavy nuclear collisions and the implied rapidity asymmetry

Abstract: We calculate pseudorapidity (η) asymmetry in pA and dA collisions in a pQCD-improved parton model. With the calculations tuned to describe existing spectra from pp collisions and asymmetric systems at midrapidity and large rapidities at FNAL and RHIC energies, we investigate the roles of nuclear shadowing and multiple scattering on the observed asymmetry. Using this framework, we make predictions for pseudorapidity asymmetries at high pT and large η in a wide range of energies up to LHC. PACS numbers: 24.85.+p… Show more

“…As in Refs. [3,66,67], the initial-state nuclear effects included in proton-nucleus or nucleus-nucleus collisions are multiple scattering and shadowing. Intrinsic transverse momentum broadening via semihard collisions is related to multiple scattering in this approach.…”
