Ks production at 62.4 GeV in STAR

摘要

1) Yields of Ks~0 from 62.4 GeV Au+Au data; 2) Exponential and Boitzmann function fits well at low p_T for Ks~0 spectra, but not well at high p_T; Then, we got the dN/dy, T & mean p_T of Ks~0; 3) dN/dy scaling with and is not perfect; 4) R_(CP) plots show the suppression, but it is not as obvious as 200 GeV; 5) The Φ's R_(CP) (from Guo-liang Ma) seems close to Ks~0, Maybe indicate a particle type dependence of the production!
