This includes the centrality and, for the first time, the pseudorapidity window dependenceof both diagonal and off-diagonal cumulants in Au+Au collisions atthe available acceptance of |\u03b7| < 0.5, the cumulants grow linearly with the pseudorapidity window. Relative to the corresponding measurements in peripheral collisions, the ratio of off-diagonal over \u221asNN = 7.7-200 GeV. Within 2 diagonal cumulants in central collisions indicates an excess correlation between net-charge and net-kaon, as well as between net-charge and net-proton. The strength of such excess correlation increasewith the collision energy. The correlation between net-proton and net-kaon multiplicity distributions \u221asNN = 200 GeV and change to positive at the lowest collision energy. Model calculations based on non-thermal (UrQMD) and thermal (HRG) production of hadrons cannot explain the data. These measurements will help map the QCD phase diagram, constrain hadron resonance gas model calculations and provide new insights on the energy dependence of is observed to be negative at baryon-strangeness correlations.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.105908.v2/t1","@type":"Dataset","description":"The dependence of efficiency corrected second-order diagonal and off-diagonal cumulants on the width of the \u03b7-window.
