Cold Nuclear Matter effects on J/\psi production at RHIC: comparing shadowing models

TL;DR

This paper compares various shadowing models to understand their impact on J/ production at RHIC, highlighting the dependence on partonic processes and comparing results with experimental data.

Contribution

It introduces a comprehensive comparison of shadowing models considering different partonic processes affecting J/ production at RHIC.

Findings

Shadowing effects vary with partonic process considered.

Results depend on the break-up cross section used.

Comparison with RHIC data shows model differences.

Abstract

We present a wide study on the comparison of different shadowing models and their influence on \jpsi production. We have taken into account the possibility of different partonic processes for the $c \bar c$-pair production. We notice that the effect of shadowing corrections on \jpsi production clearly depends on the partonic process considered. Our results are compared to the available data on \dAu collisions at RHIC energies. We try different break up cross section for each of the studied shadowing models.
