| Abstract: | The PHENIX experiment measured J/
production in pp, d + Au and Au + Au reactions at
= 200 GeV over a wide range of rapidity and transverse momentum. The nuclear modification factor obtained by comparing the
d + Au and pp cross sections as a function of rapidity, is consistent with shadowing of the gluon distribution functions.
J/
production in Au + Au collisions was compared to the production in pp collisions and it was found to be inconsistent with
models that predict strong enhancement relative to binary collision scaling.
