Charmonium suppression at RHIC and SPS: a hadronic baseline
arXiv:0901.0166 · doi:10.1016/j.physletb.2010.05.050
Abstract
A kinetic equation approach is applied to model anomalous J/psi suppression at RHIC and SPS by absorption in a hadron resonance gas which successfully describes statistical hadron production in both experiments. The puzzling rapidity dependence of the PHENIX data is reproduced as a geometric effect due to a longer absorption path for J/psi production at forward rapidity.
