Energy dependent chemical potentials of light hadrons and quarks based on transverse momentum spectra and yield ratios of negative to positive particles

Xing-Wei He, Feng-Min Wu, Hua-Rong Wei +1

We describe the transverse momentum (or mass) spectra of ${\pi }^{\pm }$, $K^{\pm }$, $p$, and $\bar{p}$ produced in central gold-gold (Au-Au), central lead-lead (Pb-Pb), and inelastic proton…
