Centrality dependence of pT spectra for identified hadrons in Au+Au and Cu+Cu collisions at √sNN= 200GeV

  • The centrality dependence of transverse momentum spectra for identified hadrons at midrapidity in Au+Au collisions at √sNN= 200GeV is systematically studied in a quark combination model. The pT spectra of π±, K±, p(p) and Λ(Λ) in different centrality bins and the nuclear modification factors (RCP) for these hadrons are calculated. The centrality dependence of the average collective transverse velocity 〈β(r)〉 for the hot and dense quark matter is obtained in Au+Au collisions, and it is applied to a relative smaller Cu+Cu collision system. The centrality dependence of pT spectra and the RCP for π0, Ks0 and Λ in Cu+Cu collisions at √sNN= 200GeV are well described. The results show that 〈β(r)〉 is only a function of the number of participants Npart and it is independent of the collision system.

Abstract: 

The centrality dependence of transverse momentum spectra for identified hadrons at midrapidity in Au+Au collisions at √sNN= 200GeV is systematically studied in a quark combination model. The pT spectra of π±, K±, p(p) and Λ(Λ) in different centrality bins and the nuclear modification factors (RCP) for these hadrons are calculated. The centrality dependence of the average collective transverse velocity 〈β(r)〉 for the hot and dense quark matter is obtained in Au+Au collisions, and it is applied to a relative smaller Cu+Cu collision system. The centrality dependence of pT spectra and the RCP for π0, Ks0 and Λ in Cu+Cu collisions at √sNN= 200GeV are well described. The results show that 〈β(r)〉 is only a function of the number of participants Npart and it is independent of the collision system.
