Is different Λ and Λ¯ polarization caused by different spatio-temporal freeze-out picture?
Thermal vorticity in non-central Au+Au collisions at energies 7.7≤s≤62.4 GeV is calculated within the UrQMD transport model. Tracing the Λ and Λ¯ hyperons back to their last interaction point we were able to obtain the temperature and the chemical potentials at the time of emission by fitting the ex...
