Chemical Potentials of Quarks Extracted from Particle Transverse Momentum Distributions in Heavy Ion Collisions at RHIC Energies

Figure 1

The transverse momentum distributions of 𝜋⁺/𝜋⁻,𝐾⁺/𝐾⁻, and 𝑝/𝑝 produced in Au-Au collisions at √𝑠_𝑁𝑁=130 GeV with different centrality classes. The symbols represent the experimental data of the PHENIX collaboration [38, 39], and the curves are our results calculated by the two-component revised Boltzmann distributions.
