Abstract
We present two methods to extract the chemical potentials of quarks in high energy collisions. The first method is based on the ratios of negatively/positively charged particles, and the temperatures extracted from the transverse momentum spectra of related hadrons are needed. The second method is based on the chemical potentials of some particles, and we also need the transverse momentum spectra of related hadrons. To extract the quark chemical potentials, we would like to propose experimental collaborations to measure simultaneously not only the transverse momentum spectra ofp-,p,K-,K+,π-, andπ+, but also those ofD-,D+,B-, andB+(even those ofΔ++,Δ-, andΩ-) in high energy nuclear collisions.
