On Extraction of Chemical Potentials of Quarks from Particle Transverse Momentum Spectra in High Energy Collisions

Figure 2

According to the solid curves in Figure 1, the calculated chemical potentials of (a) up, (b) down, and (c) strange quarks in Pb-Pb collisions at 17.3 GeV are displayed, where the solid, dashed, and dotted curves correspond to the centralities of 0–5%, 12.5–23.5%, and 33.5–80%, respectively.
