Study on the transverse-momentum spectra in 200 GeV  d+Au collisions with the Tsallis statistics

doi:10.3969/j.issn.0253-2778.2014.12.007

Abstract

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.

Key words: relativistic heavy ion collision, d+Au collision, TBW model，cold nuclear matter effect, radial flow
