Cronin effect in close-to-midrapidity regions at FNAL and RHIC energies

Research output: Contribution to journalArticle

Abstract

Cronin effect - nuclear enhancement - on pion production in pA and dAu collisions is investigated in close-to-midrapidity regions, |η| ≤ 1.5. Using a perturbative QCD improved parton model we analyze pion production in pBe and pCu collisions at energies Elab = 500, 530 and 800 GeV in fix target FNAL-E706 experiment. Next we perform calculations at RHIC collider energy, √sNN = 200 GeV, and the obtained nuclear modification factor for pions, RdAuπ is compared to experimental data by PHOBOS. Our description contains conventional nuclear shadowing and multiscattering. Magnitudes and tendencies of the measured data are reproduced properly at the above energies.
