The energy dependence of the effective temperatures of charged kaons, [Formula: see text] and [Formula: see text] produced in Au[Formula: see text]Au collisions at the Relativistic Heavy Ion Collider (RHIC) Beam Energy Scan (BES) energies are presented. At energies around [Formula: see text][Formula: see text]GeV, there is a sudden change in the energy dependence of [Formula: see text] and [Formula: see text] effective temperatures, while at higher energies a slower, continuous rise up to [Formula: see text][Formula: see text]TeV is observed. This behavior is similar with previous SPS results and could indicate the onset of deconfinement in this energy range. The [Formula: see text] effective temperatures increase with energy and no plateau-like behavior is evidenced by the data.

Balance Functions

Experiment and lattice simulation show that the quark–gluon plasma (QGP) system displays strong interaction between constituents at temperature a few times the critical temperature Tc. This QGP picture can be explained by assuming that the QGP matter above Tc is rich in different kinds of bound states, namely resonance-like QGP (RQGP). The chemical composition of the QGP system produced in ultra-relativistic heavy-ion collisions can be investigated through a general charge balance function which describes two-wave quark production during expansion afterward. In this paper, we investigate the signals of this RQGP through general charge balance functions. We find that the quasiparticles in QGP contribute a little to the balance functions because of their heavy masses. The balance functions reduce to the situation discussed before where only one-wave charge production is involved if only the quasiparticles in QGP are considered. However, the baryonic bound states in QGP have a significant effect on the balance function [Formula: see text], causing a dip in the [Formula: see text] balance function at small Δy. The existence of the binary and baryonic bound states amplify the negative dip of the balance function BpK-(Δy) at Δy ∽ 1.
