In high-energy heavy ion collisions a partonic state of matter known as the quark-gluon plasma is expected to be formed. The suppression of J/ψ meson production in high-energy heavy ion collisions is expected to be a strong signature for the formation of the quark-gluon plasma, due to Debye screening of the quark-antiquark potential. To investigate the state of matter produced in Au+Au collisions at √(sNN)=200 GeV at the PHENIX experiment, we have analyzed forward rapidity J/ψ → μ+μ- production and find that J/psi production is significantly suppressed in collisions at small impact parameter.
The analysis methods are presented here, as well as results for J/ψ invariant yields and nuclear modification factors as functions of impact parameter and J/ψ transverse momentum. The results are compared to previous J/ψ measurements in heavy ion collisions, as well as to current theoretical models, and the implications for our understanding of J/ψ production and suppression in heavy ion collisions are discussed.
