“…Figure 23: Energy dependence of the ratios of K + /π + (filled-symbols) and K − /π − (open-symbols) [234]. All results are from the top few-10% central heavy-ion collisions [206,[244][245][246][247][248]. The errors from the RHIC BES-I are the quadratic sum of statistical and systematic uncertainties where the latter dominates [234].…”

We review the present status of the search for a phase transition and critical point as well as anomalous transport phenomena in Quantum Chromodynamics (QCD), with an emphasis on the Beam Energy Scan program at the Relativistic Heavy Ion Collider at Brookhaven National Laboratory. We present the conceptual framework and discuss the observables deemed most sensitive to a phase transition, QCD critical point, and anomalous transport, focusing on fluctuation and correlation measurements. Selected experimental results for these observables together with those characterizing the global properties of the systems created in heavy ion collisions are presented. We then discuss what can be already learned from the currently available data about the QCD critical point and anomalous transport as well as what additional measurements and theoretical developments are needed in order to discover these phenomena.

“…From Table I, it is also seen that the experimentally obtained K − K + values increase with the increase of energy. It has been pointed out in [40] that the K − K + ratio increases with the energy from about 0.15 at low AGS energy [44][45][46][47][48][49][50] to about 0.5 at SPS energy [51,52] and reaches about 0.9 at RHIC energy [40]. The explanation of the energy dependence of K − K + values can be obtained from the underlying physics of kaon and anti-kaon production mechanism.…”

A detailed study of energy dependence of K − K + ratio has been carried out in nucleus-nucleus (AA) collisions (Pb+Pb collisions at √ s N N = 6.3 GeV and 17.3 GeV, Au+Au collisions at √ s N N = 19.6-200 GeV) and in pp collisions at √ s = 6.3-200 GeV in the framework of UrQMD and DPMJET III models. It has been observed that as energy increases, the K − K + ratio increases systematically for both nucleus-nucleus and pp collisions. A comparison of our analysis with the analysis of the experimental data has also been presented wherever available. Our analysis is well-supported by the experimental results obtained by different collaborations in different times.

“…The results for heavy-ion (Pb + Pb and Au + Au) collisions are plotted for comparison. The results on p + p interactions of the NA61/SHINE Collaboration at energies of the CERN SPS are shown together with the world data [19,20,[22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39]. Results on the midrapidity ratio (the top-left plot) cover the range from low energy of the SPS to the energies of the LHC.…”
