Strange and multistrange particle production in Au plus Au collisions at root s(NN)=62.4 GeV uri icon

abstract

  • We present results on strange and multistrange particle production in Au+Au collisions at sNN=62.4 GeV as measured with the STAR detector at RHIC. Midrapidity transverse momentum spectra and integrated yields of KS0, , , and and their antiparticles are presented for different centrality classes. The particle yields and ratios follow a smooth energy dependence. Chemical freeze-out parameters, temperature, baryon chemical potential, and strangeness saturation factor obtained from the particle yields are presented. Intermediate transverse momentum (pT) phenomena are discussed based on the ratio of the measured baryon-to-meson spectra and nuclear modification factor. The centrality dependence of various measurements presented show a similar behavior as seen in Au+Au collisions at s NN=200 GeV. 2011 American Physical Society.
