  • Abstract

    The blast-wave model based on the Tsallis statistics (TBW model) was used to study the particle production in 200 GeV d+Au collisions at RHIC. Light hadrons and J/Ψ transverse-momentum spectra at both mid-rapidity and forward/backward rapidity were analyzed. It was found that a non-zero radial flow for light hadrons, indicating a strong cold nuclear matter (CNM) effect in d+Au collisions. J/Ψ shows a finite radial flow at the backward rapidity. This result may imply the onset of initial state color glass condensate (CGC) in the d+Au collision system.
