Cold nuclear matter effects on J/psi production in d-Au collisions

The medium modifications of J/psi production in d-Au collisions at root(S)(NN) = 200 GeV are studied in the Glauber model. By means of the c.m. energy loss parameter per collision studied in Drell-Yan process, taking account of the inhomogeneous shadowing effect, we find that the initial-state energy loss effect can be ignored in d-Au collisions at mid-rapidity. Then, the final-state J/psi absorption effect is also considered and the theoretical results are in good agreement with the recent experimental data given by PHENIX. Finally, the experimental results of J/psi production in d-Pb collisions are also predicted at RHIC and LHC energies respectively.
