Specific Heat of Nuclear Medium Probed by KS0 Mesons Produced in Au+Au Collisions at RHIC
Original language description
The energy and centrality dependence of KS0-meson spectra measured by the STAR Collaboration at RHIC in Au+Au collisions over a wide range of √sNN=7.7-200 GeV was studied in the z-scaling approach. The scaling function ψ(z) was constructed and the self-similarity of KS0-meson production was confirmed. This observation is consistent with an abrupt decrease of the model parameter cAuAu from the value of 0.16 at √sNN=7.7 and 11.5 GeV to about 0.09 at the top RHIC energy. The scaling parameter is interpreted as a specific heat of the produced medium. The non-trivial dependence of cAuAu on the collision energy shows that KS0 meson is much more sensitive to properties of nuclear medium than a non-identified negative hadron. The irregularities in the behavior of the specific heat parameter cAuAu are considered as a possible indication of phase transition in nuclear matter.
