Light Particle and Quark Chemical Potentials from Negatively to Positively Charged Particle Yield Ratios Corrected by Removing Strong and Weak Decays

Figure 1

Yield ratios, (a) , (b) , and (c) , of negatively to positively charged particles produced in mid-(pseudo)rapidity interval in central Au-Au collisions, central Pb-Pb collisions, and INEL or NSD collisions, as well as in forward rapidity region in INEL collisions. The circles, squares, triangles, and stars without , or the symbols with and without , denote the yield ratios quoted in literature (see Table 1 for details). The circles, squares, triangles, and stars with , or the symbols with and , denote the yield ratios corrected to the primary production by removing the contributions of strong decay from high-mass resonance and weak decay from heavy flavor hadrons [8]. The curves are the results fitted by us for the dependent (see Equations (7)–(13) for details).
