Cold nuclear matter effects on the color singlet J/Ψ production in dAu collisions at energies available at the BNL Relativistic Heavy Ion Collider

We use a modified DKLMT model (M-DKLMT) to study the cold nuclear matter (CNM) effects on the color singlet J/Psi. production in dAu collisions at RHIC. The cold nuclear effect of dipole-nucleus interactions has been investigated by introducing a nuclear geometric effect function f (xi) to study the nuclear geometry distribution effect in relativistic heavy-ion collisions. The dependencies of nuclear modification factors (R-dA) on rapidity and centrality are studied and compared to experimental data. It is found that the M-DKLMT model can well describe the experimental results at both forward- and midrapidity regions in dAu collisions at RHIC.
