Possible signatures of the hadronisation scale in parton jets

Energy Dependence of String Fragmentation Function and ϕ Meson Production

“…This idea has indeed been adopted in e + e − studies quite early. [27] Recently the thermal model with two main parameters (temperature T and baryon chemical potential µ B ) was used to fit the experimental data of global hadronic yields for nucleus-nucleus collisions at SIS ( √ s nn ∼ 1 GeV), AGS, SPS, and RHIC energies, the obtained values of T and µ B are quite different from each other. [28] Therefore, for dynamical models it is also needed to consider the energy dependence of the involved dynamical ingredients properly in order to describe well the nucleus-nucleus collisions in a region spanned four energy magnitudes.…”
